Freescale Semiconductor Advance Information Document Number: MC07XSC200 Rev. 2.0, 9/2013 Dual High Side Switch (7.0 mOhm) 07XSC200 The 07XSC200 is one in a family of devices designed for low-voltage lighting or factory automation applications. Its two low RDS(ON) MOSFETs (dual 7.0 m) can control two separate 55 W / 28 W bulbs, and/or Xenon modules, and/or LEDs, and/or DC low voltage motors. Programming, control and diagnostics are accomplished using a 16-bit SPI interface. Its output with selectable slew rate improves electromagnetic compatibility (EMC) behavior. Additionally, each output has its own parallel input or SPI control for pulse-width modulation (PWM) control if desired. The 07XSC200 allows the user to program via the SPI, the fault current trip levels and duration of acceptable inrush. The device has Fail-safe mode to provide fail-safe functionality of the outputs in case of MCU damaged. The 07XSC200 is packaged in a Pb-free power-enhanced 32 pins SOIC package with exposed tab. This device is powered by SMARTMOS technology. Features • Dual 7.0 m max high side switch (at 25 °C) • Operating voltage range of 6.0 to 20 V with sleep current < 5.0 µA, extended mode from 4.0 to 28 V • 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting with daisy chain capability • PWM module using external clock or calibratable internal oscillator with programmable outputs delay management • Smart overcurrent shutdown compliant to huge inrush current, severe short-circuit, overtemperature protections with time limited auto-retry, and Fail-safe mode, in case of MCU damage • Output OFF or ON OpenLoad detection compliant to bulbs or LEDs and short to battery detection.

Its two low RDS(ON) MOSFETs (dual 7.0 m) can control two separate 55 W / 28 W bulbs and/or Xenon modules. Programming, control and diagnostics are accomplished using a 16-bit SPI interface. Its output with selectable slew rate improves electromagnetic compatibility (EMC) behavior. Additionally, each output has its own parallel input or SPI control for pulse-width modulation (PWM) control if desired. The 07XSC200 allows the user to program via the SPI, the fault current trip levels and duration of acceptable lamp inrush. The device has fail-safe mode to provide fail-safe functionality of the outputs in case of MCU damaged. 4.2 Functional Pin Description 4.2.1 Output Current Monitoring (CSNS) The Current Sense pin provides a current proportional to the designated HS0 : HS1 output or a voltage proportional to the temperature on the GND flag. That current is fed into a ground-referenced resistor (2.5 k typical) and its voltage is monitored by an MCU's A/D. The output type is selected via the SPI. This pin can be tri-stated through the SPI. 4.2.2 Direct Inputs (IN0, IN1) Each IN input wakes the device. The IN0 : IN1 high side input pins are also used to directly control HS0 : HS1 high side output pins. If the outputs are controlled by PWM module, the external PWM clock is applied to IN0 pin. These pins are to be driven with CMOS levels, and they have a passive internal pull-down, RDWN. 4.2.3 Fault Status (FSB) This pin is an open drain configured output requiring an external pull-up resistor to VDD for fault reporting. If a device fault condition is detected, this pin is active LOW. Specific device diagnostics and faults are reported via the SPI SO pin. 4.2.4 WAKE (WAKE) The WAKE input wakes the device. An internal clamp protects this pin from high damaging voltages with a series resistor (10 k typ). This input has a passive internal pull-down, RDWN. 4.2.5 PWM Clock (CLOCK) The clock input wakes the device. The PWM frequency and timing are generated from clock input by the PWM module. The clock input frequency is the selectable factor 27 = 128. This input has a passive internal pull-down, RDWN. 4.2.6 RESET (RSTB) The RESET input wakes the device. This is used to initialize the device configuration and fault registers, as well as place the device in a low-current sleep mode. The pin also starts the watchdog timer when transitioning from logic [0] to logic [1]. This pin has a passive internal pull-down, RDWN. 07XSC200 22 Analog Integrated Circuit Device Data Freescale Semiconductor 4.2.7 Chip Select (CSB) The CSB pin enables communication with the master microcontroller (MCU). When this pin is in a logic [0] state, the device is capable of transferring information to, and receiving information from, the MCU. The 07XSC200 latches in data from the Input Shift registers to the addressed registers on the rising edge of CSB. The device transfers status information from the power output to the Shift register on the falling edge of CSB. The SO output driver is enabled when CSB is logic [0]. CSB should transition from a logic [1] to a logic [0] state only when SCLK is a logic [0]. CSB has an active internal pull-up from VDD, IUP. 4.2.8 Serial Clock (SCLK) The SCLK pin clocks the internal shift registers of the 07XSC200 device. The serial input (SI) pin accepts data into the input shift register on the falling edge of the SCLK signal while the serial output (SO) pin shifts data information out of the SO line driver on the rising edge of the SCLK signal. It is important the SCLK pin be in a logic low state whenever CSB makes any transition. For this reason, it is recommended the SCLK pin be in a logic [0] whenever the device is not accessed (CSB logic [1] state). SCLK has an active internal pull-down. When CSB is logic [1], signals at the SCLK and SI pins are ignored and SO is tri-stated (highimpedance) (see Figure 10, page 26). SCLK input has an active internal pull-down, IDWN. 4.2.9 Serial Input (SI) This is a serial interface (SI) command data input pin. Each SI bit is read on the falling edge of SCLK. A 16-bit stream of serial data is required on the SI pin, starting with D15 (MSB) to D0 (LSB). The internal registers of the 07XSC200 are configured and controlled using a 5-bit addressing scheme described in Table 9, page 36. Register addressing and configuration are described in Tables 10, page 36. SI input has an active internal pull-down, IDWN. 4.2.10 Digital Drain Voltage (VDD) This pin is an external voltage input pin used to supply power to the SPI circuit. In the event VDD is lost (VDD Failure), the device goes to Fail-safe mode. 4.2.11 Ground (GND) These pins are the ground for the device. 4.2.12 Positive Power Supply (VPWR) This pin connects to the positive power supply and is the source of operational power for the device. The VPWR contact is the backside surface mount tab of the package. 4.2.13 Serial Output (SO) The SO data pin is a tri-stateable output from the shift register. The SO pin remains in a high impedance state until the CSB pin is put into a logic [0] state. The SO data is capable of reporting the status of the output, the device configuration, the state of the key inputs, etc. The SO pin changes state on the rising edge of SCLK and reads out on the falling edge of SCLK. SO reporting descriptions are provided in Table 22, page 42. 4.2.14 High Side Outputs (HS0, HS1) Protected 7.0 m high side power outputs to the load. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 23 4.2.15 Fail-safe Input (FSI) This pin incorporates an active internal pull-up current source from internal supply (VREG). This enables the watchdog time-out feature. When the FSI pin is opened, the watchdog circuit is enabled. After a watchdog time-out occurs, the output states depends on IN[0:1]. When the FSI pin is connected to GND, the watchdog circuit is disabled. The output states depends on IN[0:1] in case of VDD Failure condition, in case VDD failure detection is activated (VDD_FAIL_en bit sets to logic [1]). 4.3 Functional Internal Block Description 07XSC200 - Functional Block Diagram Power Supply MCU Interface & Output Control Self-protected High Side Switches HS0 - HS1 SPI Interface Parallel Control Inputs MCU Interface PWM Controller Supply MCU Interface & Output Control Self-protected High Side Switches Figure 9. Functional Block Diagram 4.3.1 Power Supply The 07XSC200 is designed to operate from 4.0 to 28 V on the VPWR pin. Characteristics are provided from 6.0 to 20 V for the device. The VPWR pin supplies power to internal regulator, analog, and logic circuit blocks. The VDD supply is used for Serial Peripheral Interface (SPI) communication to configure and diagnose the device. This IC architecture provides a low quiescent current sleep mode. Applying VPWR and VDD to the device will place the device in the Normal mode. The device will transit to Fail-safe mode in case of failures on the SPI or/and on VDD voltage. 4.3.2 High Side Switches: HS0–HS1 These pins are the high side outputs controlling lamps located for the front of vehicle, such as 65 W/55 W bulbs and Xenon-HID modules. N-channel MOSFETs with 7.0 m RDS(ON) are self-protected and present extended diagnostics to detect bulb outage and a short-circuit fault condition. The HS output is actively clamped during turn off of inductive loads and inductive battery line. When driving DC motor or solenoid loads demand multiple switching, an external recirculation device must be used to maintain the device in its Safe Operating Area. 07XSC200 24 Analog Integrated Circuit Device Data Freescale Semiconductor 4.3.3 MCU Interface and Output Control In Normal mode, each bulb is controlled directly from the MCU through the SPI. A pulse width modulation control module allows improvement of lamp lifetime with bulb power regulation (PWM frequency range from 100 to 400 Hz) and addressing the dimming application (day running light). An analog feedback output provides a current proportional to the load current or the temperature of the board. The SPI is used to configure and to read the diagnostic status (faults) of high side outputs. The reported fault conditions are: OpenLoad, short-circuit to battery, short-circuit to ground (overcurrent and severe short-circuit), thermal shutdown, and under/overvoltage. In Fail-safe mode, each lamp is controlled with dedicated parallel input pins. The device is configured in default mode. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 25 5 Functional Device Operation 5.1 SPI Protocol Description The SPI interface has a full duplex, three-wire synchronous data transfer with four I/O lines associated with it: Serial Input (SI), Serial Output (SO), Serial Clock (SCLK), and Chip Select (CSB). The SI / SO pins of the 07XSC200 follow a first-in first-out (D15 to D0) protocol, with both input and output words transferring the most significant bit (MSB) first. All inputs are compatible with 5.0 or 3.3 V CMOS logic levels.

IN_ON[x] internal signal The 07XSC200 transits to operating modes according to the following signals: • wake-up = RSTB or WAKE or IN_ON[0] or IN_ON[1] or CLOCK_ON, • fail = (VDD Failure and VDD_FAIL_en) or (Watchdog time-out and FSI input not shorted to ground), • fault = OC[0:1] or OT[0:1] or SC[0:1] or UV or (OV and OV_dis). 07XSC200 26 Analog Integrated Circuit Device Data Freescale Semiconductor Table 5. 07XSC200 Operating Modes Mode wake-up fail fault Comments Sleep 0 x x Device is in Sleep mode.

Operating Modes 5.2.1 Sleep Mode The 07XSC200 is in Sleep mode when: • VPWR and VDD are within the normal voltage range, • wake-up = 0, • fail = X, • fault = X. This is the Default mode of the device after first applying battery voltage (VPWR) prior to any I/O transitions. This is also the state of the device when the WAKE and RSTB, CLOCK_ON and IN_ON[0:1] are logic [0]. In the Sleep mode, the output and all unused internal circuitry, such as the internal regulator, are off to minimize draw current. In addition, all SPI-configurable features of the device are as if set to logic [0]. In the event of an external VPWR supply disconnect, an unexpected current consumption may sink on the VDD supply pin (In Sleep state). This current leakage is about 70 mA instead of 5.0 µA and it may impact the device reliability. The device recovers its normal operational mode once VPWR is reconnected. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 27 To avoid this unexpected current leakage on the VDD supply pin, maintain the device in Normal mode with RSTB pin set to logic[1]. This will allow diagnosis of the battery disconnection event through UV fault reporting in SPI. Then, apply 0 V on the VDD supply pin to switch the device to Sleep state. 5.2.2 Normal Mode The 07XSC200 is in Normal mode when: • VPWR and VDD are within the normal voltage range, • wake-up = 1, • fail = 0, • fault = 0. In this mode, the NM bit is set to lfault_contrologic [1] and the outputs HS[0:1] are under control, as defined by the hson signal: hson[x] = (((IN[x] and DIR_dis[x]) or On bit[x]) and PWM_en) or (On bit [x] and Duty_cycle[x] and PWM_en). In this mode and also in Fail-safe, the fault condition reset depends on fault_control signal, as defined below: fault_control[x] = ((IN_ON[x] and DIR_dis[x]) and PWM_en) or (On bit [x]). 5.2.2.1 Programmable PWM Module The outputs HS[0:1] are controlled by the programmable PWM module if PWM_en and On bits are set to logic [1]. The clock frequency from CLOCK input pin or from the internal clock is the factor 27 (128) of the output PWM frequency (CLOCK_sel bit). The outputs HS[0:1] can be controlled in the range of 5.0 to 98% with a resolution of 7 bits of duty cycle (Table 6). The state of other IN pin is ignored. Table 6. Output PWM Resolution On bit Duty cycle Output state 0 X OFF 1 0000000 PWM (1/128 duty cycle) 1 0000001 PWM (2/128 duty cycle) 1 0000010 PWM (3/128 duty cycle) 1 n PWM ((n+1)/128 duty cycle) 1 1111111 fully ON The timing includes seven programmable PWM switching delay (number of PWM clock rising edges) to improve overall EMC behavior of the light module (Table 7). Table 7.

In case of clock failure, no PWM feature is provided, the On bit defines the outputs state and the CLOCK_fail bit reports [1]. 5.2.2.2 Calibratable Internal Clock The internal clock can vary as much as 30 percent corresponding to typical fPWM(0) output switching period. Using the existing SPI inputs and the precision timing reference already available to the MCU, the 07XSC200 allows clock period setting within 10 percent of accuracy. Calibrating the internal clock is initiated by defined word to CALR register. The calibration pulse is provided by the MCU. The pulse is sent on the CSB pin after the SPI word is launched. At the moment, the CSB pin transitions from logic [1] to [0] until from logic [0] to [1] determines the period of internal clock with a multiplicative factor of 128. CS SI CALR SI command ignored Internal clock duration In case a negative CSB pulse is outside a predefined time range (from t CSB(MIN) to t CSB(MAX)), the calibration event will be ignored and the internal clock will be unaltered or reset to the default value (fPWM(0)), if this was not calibrated before. The calibratable clock is used, instead of the clock from CLOCK input, when CLOCK_sel is set to [1]. 5.2.3 Fail-safe Mode The 07XSC200 is in Fail-safe mode when: • VPWR is within the normal voltage range, • wake-up = 1, • fail = 1, • fault = 0. 5.2.3.1 Watchdog If the FSI input is not grounded, the watchdog time-out detection is active when either the WAKE or IN_ON[0:1] or RSTB input pin transitions from logic [0] to logic [1]. The WAKE input is capable of being pulled up to VPWR with a series of limiting resistance limiting the internal clamp current according to the specification. The watchdog time-out is a multiple of an internal oscillator. As long as the WD bit (D15) of an incoming SPI message is toggled within the minimum watchdog time-out period (WDTO), the device will operate normally. 5.2.3.2 Fail-safe Conditions If an internal watchdog time-out occurs before the WD bit for FSI open (Table 8) or in case of VDD failure condition (VDD< VDD(FAIL))) for VDD_FAIL_en bit is set to logic [1], the device will revert to a Fail-safe mode until the WD bit is written to logic [1] (see fail-safe to normal mode transition paragraph) and VDD is within the normal voltage range. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 29 Table 8. SPI Watchdog Activation Typical RFSI () Watchdog 0 (shorted to ground) Disabled (open) Enable During the Fail-safe mode, the outputs will depend on the corresponding input. The SPI register content is reset to their default value (except POR bit) and fault protections are fully operational. The Fail-safe mode can be detected by monitoring the NM bit is set to [0]. 5.2.4 Normal & Fail-safe Mode Transitions Transition Fail-safe to Normal mode To leave the Fail-safe mode, VDD must be in nominal voltage and the microcontroller has to send a SPI command with WDIN bit set to logic [1]; the other bits are not considered. The previous latched faults are reset by the transition into Normal mode (autoretry included). Moreover, the device can be brought out of the Fail-safe mode due to watchdog time-out issue by forcing the FSI pin to logic [0]. Transition Normal to Fail-safe mode To leave the Normal mode, a fail-safe condition must occurred (fail=1). The previous latched faults are reset by the transition into Fail-safe mode (auto-retry included). 5.2.5 Fault Mode The 07XSC200 is in Fault mode when: • VPWR and VDD are within the normal voltage range, • wake-up = 1, • fail = X, • fault=1. This device indicates the faults below as they occur by driving the FSB pin to logic [0] for RSTB input is pulled up: • Overtemperature fault, • Overcurrent fault, • Severe short-circuit fault, • Output(s) shorted to VPWR fault in OFF state, • OpenLoad fault in OFF state, • Overvoltage fault (enabled by default), • Undervoltage fault. The FSB pin will automatically return to logic [1] when the fault condition is removed, except for overcurrent, severe short-circuit, overtemperature and undervoltage which will be reset by a new turn-on command (each fault_control signal to be toggled). Fault information is retained in the SPI fault register and is available (and reset) via the SO pin during the first valid SPI communication. The OpenLoad fault in ON state is only reported through SPI register without effect on the corresponding output state (HS[x]) and the FS pin. 5.2.6 Start-up Sequence The 07XSC200 enters in Normal mode after start-up if following sequence is provided: • VPWR and VDD power supplies must be above their undervoltage thresholds, • generate wake-up event (wake-up=1) from 0 to 1 on RSTB. The device switches to normal mode with SPI register content is reset (as defined in Table 10 and Table 22). All features of the 07XSC200 will be available after 50 s typical, and all SPI registers are set to default values (set to logic [0]). • toggle WD bit from 0 to 1. And, in case the PWM module is used (PWM_en bit is set to logic [1]) with an external reference clock: 07XSC200 30 Analog Integrated Circuit Device Data Freescale Semiconductor • apply PWM clock on CLOCK input pin after maximum 200s (min. 50s). If the correct start-up sequence is not provided, the PWM function is not guaranteed. 5.3 Protection and Diagnostic Features 5.3.1 Protections Over-temperature Fault The 07XSC200 incorporates over-temperature detection and shutdown circuitry for each output structure. Two cases need to be considered when the output temperature is higher than TSD: • If the output command is ON: the corresponding output is latched OFF. FSB will be also latched to logic [0]. To delatch the fault and be able to turn ON again the outputs, the failure condition must disappear and the auto-retry circuitry must be active, or the corresponding output must be commanded OFF and then ON (toggling fault_control signal of corresponding output) or the VSUPPLY(POR) condition, if VDD = 0. • If the output command is OFF: FSB will go to logic [0] till the corresponding output temperature are below TSD. For both cases, the fault register OT[0:1] bit into the status register will be set to [1]. The fault bits will be cleared in the status register after a SPI read command. 5.3.1.1 Overcurrent Fault The 07XSC200 incorporates output shutdown in order to protect each output structure against resistive short-circuit condition. This protection is composed by eight predefined current levels (time dependent) to fit Xenon-HID manners by default or, 55 W or 28 W bulb profiles, selectable separately by Xenon bit and 28W bits (as illustrated Figure 14, page 39). In the first turn-on, the lamp filament is cold and the current will be huge. fault_control signal transition from logic [0] to [1] or an auto-retry define this event. In this case, the overcurrent protection will be fitted to inrush current, as shown in Figure 5. This overcurrent protection is programmable: OC[1:0] bits select overcurrent slope speed and OCHI1 current step can be removed in case the OCHI bit is set to [1]. Over-current thresholds fault_control hson signal hson PWM In Steady state, the wire harness will be protected by OCLO2 current level by default. Three other DC overcurrent levels are available: OCLO1 or OCLO3 or OCLO4 based on the state of the OCLO[1,0] bits. If the load current level ever reaches the overcurrent detection level, the corresponding output will latch the output OFF and FSB will be also latched to logic [0]. To delatch the fault and be able to turn ON again the corresponding output, the failure condition must disappear and the auto-retry circuitry must be active or the corresponding output must be commanded OFF and then ON (toggling fault_control signal of corresponding output) or VSUPPLY(POR) condition if VDD = 0. The SPI fault report (OC[0:1] bits) is removed after a read operation. In Normal mode using internal PWM module, the 07XSC200 incorporates also a cooling bulb filament management if OC_mode and Xenon are set to logic [1]. In this case, the firstt step of multi-step overcurrent protection will depend to the previous OFF duration, as illustrated in Figure 6. The following figure illustrates the current level will be used in function to the duration of previous OFF state (toff). The slope of cooling bulb emulator is configurable with OCOFFCB[1:0] bits. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 31 Depending on toff depending to toff Over-current thresholds Cooling toff fault_control hson signal hson PWM 5.3.1.2 Severe Short-circuit Fault The 07XSC200 provides output shutdown to protect each output in case of a severe short-circuit during of the output switching. If the short-circuit impedance is below RSHORT, the device will latch the output OFF, FSB will go to logic [0] and the fault register SC[0:1] bit will be set to [1]. To delatch the fault and be able to turn ON again the outputs, the failure condition must disappear and the corresponding output must be commanded OFF and then ON (toggling fault_control signal of corresponding output) or VSUPPLY(POR) condition if VDD = 0. The SPI fault report (SC[0:1] bits) is removed after a read operation. 5.3.1.3 Overvoltage Fault (Enabled by Default) By default, the overvoltage protection is enabled. The 07XSC200 shuts down all outputs and FSB will go to logic [0] during an overvoltage fault condition on the VPWR pin (VPWR > VPWR(OV)). The outputs remain in the OFF state until the overvoltage condition is removed (VPWR < VPWR(OV) - VPWR(OVHYS)). When experiencing this fault, the OVF fault bit is set to logic [1] and cleared after either a valid SPI read. The overvoltage protection can be disabled through the SPI (OV_dis bit is disabled set to logic [1]). The fault register reflects any overvoltage condition (VPWR > VPWR(OV)). This overvoltage diagnosis, as a warning, is removed after a read operation, if the fault condition disappears. The HS[0:1] outputs are not commanded in RDS(ON) above the OV threshold. 5.3.1.4 Undervoltage Fault The output(s) will latch off at some battery voltage below VPWR(UV). As long as the VDD level stays within the normal specified range, the internal logic states within the device will remain (configuration and reporting). In the case where battery voltage drops below the undervoltage threshold (VPWR < VPWR(UV)), the outputs will turn off, FSB will go to logic [0], and the fault register UV bit will be set to [1]. Two cases need to be considered when the battery level recovers (VPWR > VPWR(UV)_UP): • If outputs command are low, FSB will go to logic [1] but the UV bit will remain set to 1 until the next read operation (warning report). • If the output command is ON, FSB will remain at logic [0]. To delatch the fault and be able to turn ON again the outputs, the failure condition must disappear and the auto-retry circuitry must be active or the corresponding output must be commanded OFF and then ON (toggling fault_control signal of corresponding output) or VSUPPLY(POR) condition if VDD = 0. In extended mode, the output is protected by overtemperature shutdown circuitry. All previous latched faults, occurred when VPWR was within the normal voltage range, are guaranteed if VDD is within the operational voltage range or until VSUPPLY(POR) if VDD = 0. Any new OT fault is detected (VDD failure included) and reported through SPI above VPWR(UV). The output state is not changed as long as the VPWR voltage does not drop any lower than 3.5 V typical. All latched faults (overtemperature, overcurrent, severe short-circuit, over and undervoltage) are reset if: • VDD < VDD(FAIL) with VPWR in nominal voltage range, • VDD and VPWR supplies is below VSUPPLY(POR) voltage value. 07XSC200 32 Analog Integrated Circuit Device Data Freescale Semiconductor (fault_control=0) (OpenloadOFF=1 or ShortVpwr=1 or OV=1) (fault_control=1 and OV=0) OFF if hson=0 ON (fault_control=0 or OV=1) (fault_control=0) (OpenloadOFF=1 or ShortVpwr=1 or OV=1) (OpenloadON=1) (SC=1) if hson=1 (Retry=1) Latched OFF (count=16) (SC=1) (OpenloadON=1) (after Retry Period and OV=0) Auto-retry (OV=1) OFF Auto-retry ON if hson=1 (OpenloadOFF=1 or ShortVpwr=1 or OV=1) (Retry=1) => count=count+1 (fault_control=0) Figure 13. Auto-retry State Machine 5.3.2 Auto-retry The auto-retry circuitry is used to reactivate the output(s) automatically in case of overcurrent or overtemperature or undervoltage failure conditions to provide a high availability of the load. Auto-retry feature is available in Fault mode. It is activated in case of internal retry signal is set to logic [1]: retry[x] = OC[x] or OT[x] or UV. The feature retries to switch-on the output(s) after one auto-retry period (tAUTO) with a limitation in term of number of occurrence (16 for each output). The counter of retry occurrences is reset in case of Fail-safe to Normal or Normal to Fail-safe mode transitions. At each auto-retry, the overcurrent detection will be set to default values in order to sustain the inrush current. The Figure 13 describes the auto-retry state machine. 5.3.3 Diagnostic Output Shorted to VPWR Fault The 07XSC200 incorporates output shorted to VPWR detection circuitry in OFF state. Output shorted to VPWR fault is detected if output voltage is higher than VOSD(THRES) and reported as a fault condition when the output is disabled (OFF). The output shorted to VPWR fault is latched into the status register after the internal gate voltage is pulled low enough to turn OFF the output. The OS[0:1] and OL_OFF[0:1] fault bits are set in the status register and FSB pin reports in real time the fault. If the output shorted to VPWR fault is removed, the status register will be cleared after reading the register. The open output shorted to VPWR protection can be disabled through SPI (OS_DIS[0:1] bit). OpenLoad Faults The 07XSC200 incorporates three dedicated OpenLoad detection circuitries on the output to detect in OFF and in ON state. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 33 5.3.3.1 OpenLoad Detection in Off State The OFF output OpenLoad fault is detected when the output voltage is higher than VOLD(THRES) pulled up with internal current source (IOLD(OFF)) and reported as a fault condition when the output is disabled (OFF). The OFF Output OpenLoad fault is latched into the status register or when the internal gate voltage is pulled low enough to turn OFF the output. The OL_OFF[0:1] fault bit is set in the status register. If the OpenLoad fault is removed (FSB output pin goes to high), the status register will be cleared after reading the register. The OFF output OpenLoad protection can be disabled through SPI (OLOFF_DIS[0:1] bit). 5.3.3.2 OpenLoad Detection in On State The ON output OpenLoad current thresholds can be chosen by the SPI to detect a standard bulbs or LEDs (OLLED[0:1] bit set to logic [1]). In the case where load current drops below the defined current threshold OLON bit is set to logic [1], the output stays ON and FSB is not disturbed. 5.3.3.3 OpenLoad Detection in On State For Led OpenLoad for LEDs only (OLLED[0:1] set to logic [1]) is detected periodically each t OLLED (fully-on, D[6:0]=7F). To detect OLLED in fully-on state, the output must be ON at least t OLLED. To delatch the diagnosis, the condition should be removed and the SPI read operation is needed (OL_ON[0:1] bit). The ON output open-load protection can be disabled through the SPI (OLON_DIS[0:1] bit). 5.3.3.4 Analog Current Recopy and Temperature Feedbacks The CSNS pin is an analog output reporting a current proportional to the designed output current or a voltage proportional to the temperature of the GND flag (pin #14). The routing is SPI programmable (TEMP_en, CSNS_en, CSNS_s[1,0] and CSNS_ratio_s bits). In case the current recopy is active, the CSNS output delivers current only during ON time of the output switch without overshoot. The maximum current is 2.0 mA, typical. The typical value of external CSNS resistor connected to the ground is 2.5 k. The current recopy is not active in Fail-safe mode. 5.3.3.5 Temperature Prewarning Detection In Normal mode, the 07XSC200 provides a temperature prewarning reported via the SPI, in case the temperature of the GND flag is higher than TOTWAR. This diagnosis (OTW bit set to [1]) is latched in the SPI DIAGR0 register. To delatch, a read SPI command is needed. 5.3.4 Active Clamp ON VPWR The device provides an active gate clamp circuit in order to limit the maximum transient VPWR voltage at VPWR(CLAMP). In case of an overload on an output, the corresponding output is turned off, which leads to high voltage at VPWR with an inductive VPWR line. When the VPWR voltage exceeds VPWR(CLAMP) threshold, the turn-off on the corresponding output is deactivated and all HS[0:1] outputs are switched ON automatically to demagnetize the inductive battery line. 5.3.5 Reverse Battery on VPWR The output survives the application of reverse voltage as low as -18 V. Under these conditions, the ON resistance of the output is two times higher than a typical ohmic value in forward mode. No additional passive components are required except on the VDD current path. 07XSC200 34 Analog Integrated Circuit Device Data Freescale Semiconductor 5.3.6 Ground Disconnect Protection In the event the 07XSC200 ground is disconnected from load ground, the device protects itself and safely turns OFF the output, regardless of the state of the output at the time of disconnection (maximum VPWR = 16 V). A 10 k resistor needs to be added between the MCU and each digital input pin to ensure the device turns off, during a ground disconnect and to prevent this pin from exceeding maximum ratings. 5.3.7 5.3.7.1 Loss of Supply Lines Loss of VDD If the external VDD supply is disconnected (or not within specification: VDD < VDD(FAIL), with the VDD_FAIL_en bit set to logic [1]), all SPI register content is reset. The outputs can still be driven by the direct inputs IN[0 : 1] if VPWR is within specified voltage range. The 07XSC200 uses the battery input to power the output MOSFET-related current sense circuitry and any other internal logic providing Fail-safe device operation with no VDD supplied. In this state, the overtemperature, overcurrent, severe short-circuit, short to VPWR and OFF OpenLoad circuitry are fully operational, with default values corresponding to all SPI bits are set to logic [0]. No current is conducted from VPWR to VDD. 5.3.7.2 Loss of VPWR If the external VPWR supply is disconnected (or not within specification), the SPI configuration, reporting, and daisy chain features are provided for RSTB to set to logic [1] under VDD in nominal conditions. This fault condition can be diagnosed with UV fault in SPI STATR_s registers. The SPI pull-up and pull-down current sources are not operational. The previous device configuration is maintained. No current is conducted from VDD to VPWR. 5.3.7.3 Loss of VPWR and VDD If the external VPWR and VDD supplies are disconnected (or not within specification: (VDD and VPWR) < VSUPPLY(POR)), all SPI register contents are reset, with default values corresponding to all SPI bits set to logic [0] and all latched faults reset. 5.3.8 EMC Performances All following tests are performed on the Freescale evaluation board in accordance with the typical application schematic. The device is protected in the event of positive and negative transients on the VPWR line (per ISO 7637-2). The 07XSC200 successfully meets the Class 5 of the CISPR25 emission standard and 200 V/m or BCI 200 mA injection level for immunity tests. 5.4 Logic Commands and Registers 5.4.1 Serial Input Communication SPI communication is accomplished using 16-bit messages. A message is transmitted by the MCU starting with the MSB D15 and ending with the LSB, D0 (Table 9). Each incoming command message on the SI pin can be interpreted using the following bit assignments: the MSB, D15, is the watchdog bit (WDIN). In some cases, output selection is done with bit D13. The next four bits, D14 -D12: D10, are used to select the command register. The remaining nine bits, D8 : D0, are used to configure and control the outputs and their protection features. Multiple messages can be transmitted in succession to accommodate those applications where daisy-chaining is desirable, or to confirm transmitted data, as long as the messages are all multiples of 16 bits. Any attempt made to latch in a message that is not 16 bits will be ignored. The 07XSC200 has defined registers, which are used to configure the device and to control the state of the outputs. Table 10 summarizes the SI registers. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 35 Table 9.

The register bits D[4:0] determine the content of the first sixteen bits of SO data. In addition to the device status, this feature provides the ability to read the content of the PWMR_s, CONFR0_s, CONFR1_s, OCR_s, GCR and CALR registers (Refer to Serial Output Communication (Device Status Return Data). 5.4.2.2 Address A1A0001— Output PWM Control Register (PWMR_s) The PWMR_s register allows the MCU to control the state of corresponding output through the SPI. Each output “s” is independently selected for configuration based on the state of the D13 bit (Table 11). Table 11. Output Selection A (D13) HS Selection 0 HS0 (default) 1 HS1 A logic [1] on bit D8 (28W_s) selects the 28 W overcurrent protection profile: the overcurrent thresholds are divided by 2, and the inrush and cooling responses are dedicated to 28 W lamps for HS[0,1] outputs. Bit D7 sets the output state. A logic [1] enables the corresponding output switch and a logic [0] turns it OFF (if IN input is also pulled down). Bits D6:D0 set the output PWM duty cycle to one of 128 levels for PWM_en is set to logic [1], as shown Table 6. 5.4.2.3 Address A1A0010— Output Configuration Register (CONFR0_S) The CONFR0_s register allows the MCU to configure corresponding output switching through the SPI. Each output “s” is independently selected for configuration based on the state of the D14 : D13 bits (Table 11). For the selected output, a logic [0] on bit D5 (DIR_DIS_s) will enable the output for direct control. A logic [1] on bit D5 will disable the output from direct control (in this case, the output is only controlled by the On bit). D4:D3 bits (SR1_s and SR0_s) are used to select the high or medium or low speed slew rate for the selected output, the default value [00] corresponds to the medium speed slew rate (Table 12). Table 12. Slew Rate Speed Selection SR1_s (D4) SR0_s (D3) Slew Rate Speed 0 0 medium (default) 0 1 low 1 0 high 1 1 Not used Incoming message bits D2 : D0 reflect the desired output that will be delayed of predefined PWM clock rising edges number, as shown Table 7, (only available for PWM_en bit is set to logic [1]). 5.4.2.4 Address A1A0011 — Output Configuration Register (CONFR1_s) The CONFR1_s register allows the MCU to configure corresponding output fault management through the SPI. Each output “s” is independently selected for configuration based on the state of the D14 : D13 bits (Table 11). A logic [1] on bit D6 (RETRY_unlimited_s) disables the auto-retry counter for the selected output, the default value [0] corresponds to enable auto-retry feature with time limitation. 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 37 A logic [1] on bit D5 (RETRY_dis_s) disables the auto-retry for the selected output, the default value [0] corresponds to enable this feature. A logic [1] on bit D4 (OS_dis_s) disables the output hard shorted to VPWR protection for the selected output, the default value [0] corresponds to enable this feature. A logic [1] on bit D3 (OLON_dis_s) disables the ON output OpenLoad detection for the selected output, the default value [0] corresponds to enable this feature (Table 13). A logic [1] on bit D2 (OLOFF_dis_s) disables the OFF output OpenLoad detection for the selected output, the default value [0] corresponds to enable this feature. A logic [1] on bit D1 (OLLED_en_s) enables the ON output OpenLoad detection for LEDs for the selected output, the default value [0] corresponds to ON output OpenLoad detection is set for bulbs (Table 13). Table 13. ON OpenLoad Selection OLON_dis_s (D3) OLLED_en_s (D1) 0 0 enable with bulb threshold (default) 0 1 enable with LED threshold 1 X disable ON OpenLoad detection A logic [1] on bit D0 (CSNS_ratio_s) selects the high ratio on the CSNS pin for the corresponding output. The default value [0] is the low ratio (Table 14). Table 14. Current Sense Ratio Selection 5.4.2.5 CSNS_high_s (D0) Current Sense Ratio 0 CRS0 (default) 1 CRS1 Address A1A0100 — Output Overcurrent Register (OCR) The OCR_s register allows the MCU to configure corresponding output overcurrent protection through the SPI. Each output “s” is independently selected for configuration based on the state of the D14 : D13 bits (Table 11). A logic [1] on bit D8 (Xenon_s) disables enables the Xenon 55 W or 28 W bulb overcurrent profile, as described Figure 14. 07XSC200 38 Analog Integrated Circuit Device Data Freescale Semiconductor Xenon bit set to logic [0]: IOCH1 IOCH2 IOC1 IOC2 IOCLO4 IOCLO3 IOCLO2 IOCLO1 t OC1 t OC3 t OC4 t OC5 t OC2 t OC6 Time t OC7 Xenon bit set to logic [1]: IOCH1 IOCH2 IOC1 IOC2 IOC3 IOC4 IOCL4 IOCL3 IOCL2 IOCL1 t OC1 t OC3 t OC4 t OC5 t OC2 t OC6 Time t OC7 Figure 14.

Bit D8 allows the MCU to enable or disable the VDD failure detector. A logic [1] on VDD_FAIL_en bit allows switch of the outputs HS[0:1] with PWMR register device in Fail-safe mode in case of VDD < VDD(FAIL). Bit D7 allows the MCU to enable or disable the PWM module. A logic [1] on PWM_en bit allows control of the outputs HS[0:1] with PWMR register (the direct input states are ignored). Bit D6 (CLOCK_sel) allows to select the clock used as reference by PWM module, as described in the following Table 19. Table 19. PWM Module Selection PWM_en (D7) CLOCK_sel (D6) PWM module 0 X PWM module disabled (default) 1 0 PWM module enabled with external clock from CLOCK 1 1 PWM module enabled with internal calibrated clock Bits D5:D4 allow the MCU to select one of two analog feedback on CSNS output pin, as shown in Table 20. 07XSC200 40 Analog Integrated Circuit Device Data Freescale Semiconductor Table 20.

When this bits is [0], the overvoltage is enabled (default value). 5.4.2.6 Address 00111 — Calibration Register (CALR) The CALR register allows the MCU to calibrate internal clock, as explained in Figure 13. 5.4.3 Serial Output Communication (Device Status Return Data) When the CSB pin is pulled low, the output register is loaded. Meanwhile, the data is clocked out MSB- (OD15-) first as the new message data is clocked into the SI pin. The first sixteen bits of data clocking out of the SO, and following a CSB transition, is dependent upon the previously written SPI word. Any bits clocked out of the Serial Output (SO) pin after the first 16 bits will be representative of the initial message bits clocked into the SI pin since the CSB pin first transitioned to a logic [0]. This feature is useful for daisy-chaining devices as well as message verification. A valid message length is determined following a CSB transition of [0] to [1]. If there is a valid message length, the data is latched into the appropriate registers. A valid message length is a multiple of 16 bits. At this time, the SO pin is tri-stated and the fault status register is now able to accept new fault status information. SO data will represent information ranging from fault status to register contents, user selected by writing to the STATR bits OD4, OD3, OD2, OD1, and OD0. The value of the previous bit SOA3 will determine which output the SO information applies to for the registers which are output specific; viz., Fault, PWMR, CONFR0, CONFR1, and OCR registers. Note that the SO data will continue to reflect the information for each output that was selected during the most recent STATR write until changed with an updated STATR write. The output status register correctly reflects the status of the STATR-selected register data at the time that the CSB is pulled to a logic [0] during SPI communication, and/or for the period of time since the last valid SPI communication, with the following exception: • The previous SPI communication was determined to be invalid. In this case, the status will be reported as though the invalid SPI communication never occurred • The VPWR voltage is below 4.0 V, the status must be ignored by the MCU 5.4.4 Serial Output Bit Assignment The 16 bits of serial output data depend on the previous serial input message, as explained in the following paragraphs. Table 22, summarizes SO returned data for bits OD15 : OD0. • • • • Bit OD15 is the MSB; it reflects the state of the watchdog bit from the previously clocked-in message Bits OD14:OD10 reflect the state of the bits SOA4 : SOA0 from the previously clocked in message Bit OD9 is set to logic [1] in Normal mode (NM) The contents of bits OD8 : OD0 depend on bits D4 : D0 from the most recent STATR command SOA4 : SOA0 as explained in the paragraphs following Table 22 07XSC200 Analog Integrated Circuit Device Data Freescale Semiconductor 41 Table 22.
