Freescale Semiconductor Technical Data Document Number: MC06XS3517 Rev. 5.0, 4/2014 Smart High-side Switch Module (Triple 6.0 mOhm and Dual 17 mOhm) 06XS3517 The 06XS3517 device is a five channel 12 V high-side switch module with integrated control and a high number of protective and diagnostic functions. It is designed for automotive lighting and industrial applications. The low RDS(on) channels (three 6.0 mOhm, two 17 mOhm) can control different types of lighting applications; bulbs, Xenon-HID lights, and LEDs. Control, device configuration, and diagnostics are performed through a 16-bit SPI interface (3.3 V or 5.0 V). When communication with the external microcontroller or VDD is lost, the device enters a fail-safe operation mode, but remains operational, controllable, and protected. The channels are controlled by an external clock signal and allow staggered switch-on delay, to improve EMC performances. Programmable output voltage slew rates (individually programmable) further help improve EMC performance. To avoid shutting off the device upon inrush current while still being able to closely track the load current, a dynamic overcurrent threshold profile is featured. Load current in each channel can be sensed. The duty cycle of the channels can be controlled independently and the switching frequency of each of them can be doubled. The 06XS3517 is housed in a non-leaded Power QFN package with an exposed pad. This device is powered using SMARTMOS technology.

Current Sensing Time Delays MC06XS3517 Analog Integrated Circuit Device Data Freescale Semiconductor 19 FUNCTIONAL DESCRIPTION INTRODUCTION FUNCTIONAL DESCRIPTION INTRODUCTION The 06XS3517 is designed for low-voltage automotive and industrial lighting applications. Its five low RDS(on) MOSFETs (three 6.0 mOhm and two 16 mOhm) can control the high- sides of five separate resistive loads (bulbs). Programming, control, and diagnostics are accomplished using a 16-bit SPI interface. FUNCTIONAL PIN DESCRIPTION SUPPLY VOLTAGE (VBAT) The VBAT pin of the 06XS3517 is the power supply of the device. In addition to its supply function, this tab contributes to the thermal behavior of the device by conducting the heat from the switching MOSFETs to the printed circuit board. SUPPLY VOLTAGE (VCC) The timing includes four programmable PWM switching phases (0°, 90°, 180°, and 270°) to improve overall EMC behavior of the light module. As an example: When the load currents have equal amplitude, the amplitude of the input current is divided by four, while the ripple frequency is 4 times the original. The two following pictures illustrate this behavior. This is an external voltage input pin used to supply the digital portion of the circuit and the gate driver of the external smart MOSFET. GROUND (GND) This pin is the ground of the device. CLOCK INPUT / WAKE-UP OUTPUT (CLOCK) When the part is in Normal mode (RST=1), the PWM frequency and timing are generated from the rising edge of clock input by the PWM module. The clock input frequency is the selectable factor 27 = 128 or 28 = 256 of the PWM frequency per output, depending PR bit value. The OUT1:6 can be controlled in the range of 4% to 96% with a resolution of 7 bits of the duty cycle (bits D[6:0]). Figure 6 describes the PWM resolution. Table 6. PWM Resolution On/Off (Bit D7) Duty cycle (7 bits resolution) 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 1111111 fully ON • With the following SPI configuration: D7:D0=FF. • In case of clock input signal failure (out of f PWM), the outputs state depends of D7 bit value (D7 = 1 = ON) in Normal mode. In Fail mode, the ouputs state depend on IGN, FLASHER, and FOG pins. The synchronization of the switching phases between different IC is provided by a SPI command in combination with the CSB input. The bit in the SPI is called PWM sync (initialization register). In Normal mode, no PWM feature (100% duty cycle) is provided in the following instances: If RSTB = 0, this pin reports the wake-up event for wake=1 when VBAT and VCC are in operational voltage range. LIMP HOME INPUT (LIMP) The Fail mode of the component can be activated by this digital input port. The signal is “high active”, meaning the Fail mode can be activated by a logic high signal at the input. MC06XS3517 20 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION IGNITION INPUT (IGN) FET OUT OUTPUT (FETOUT) The ignition input wakes the device. It also controls the Fail mode activation. The signal is “high active”, meaning the component is active in case of a logic high at the input. This output pin can be used to control an external smart MOSFET (OUT6) at a logic level (1 = ON, 0 = OFF). The high level of the FETOUT Output is VCC, if VBAT and VCC are available, in case FETOUT is a controlled ON. FETOUT is not protected if there is a short-circuit or undervoltage on VBAT. In case of a reverse battery, OUT6 is OFF. FLASHER INPUT (FLASHER) The flasher input wakes the device. It also controls the Fail Mode activation. The signal is “high active”, meaning the component is active in case of a logic high at the input. FOG INPUT (FOG) The fog input wakes the device. It also controls the Fail Mode activation. The signal is “high active”, meaning the component is active in case of a logic high at the input. RESET INPUT (RSTB) This input wakes the device when the RSTB pin is at logic [1]. It is also used to initialize the device configuration and the SPI faults registers when the signal is low. All SI/SO registers described Table 9 and Table 12 are reset. The fault management is not affected by RSTB (see Figure 2). CURRENT SENSE OUTPUT (CSNS) The current sense output pin is an analog current output or a voltage proportional to the temperature on the GND flag. The routing to the external resistor is SPI programmable. This current sense monitoring may be synchronized in case of the OUT6 is not used. The CSNS output is valid after a rising edge on the FETOUT pin (after tsync(val) s.) if the CSNS sync SPI bit was set to logic [0] and remains valid till a falling edge is generated. Connection of the FETOUT pin to a MCU input pin allows the MCU to sample the CSNS pin during a valid time slot. Since this falling edge is generated at the end of this time slot, upon a switch-off command, this feature may be used to implement maximum current control. CHARGE PUMP (CP) An external capacitor must be connected between the CP and the VBAT pin. It is used as a tank for the internal charge pump. Its value is 100 nF ± 20%, 25 V maximum. FET IN INPUT (FETIN) This input pin receives the current recopy from an external smart MOSFET. It can be routed on CSNS output by a SPI command. SPI PROTOCOL DESCRIPTION The SPI interface has a full-duplex, three-wire, synchronous data transfer with four I/O lines associated with it: Serial Clock (SCLK), Serial Input (SI), Serial Output (SO), and Chip Select (CSB). The SI/SO pins of the 06XS3517 device 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 3.3 V and 5.0 V CMOS logic levels, supplied by VCC. The SPI lines perform the following functions: SERIAL CLOCK (SCLK) The SCLK pin clocks the internal shift registers of the 06XS3517 device. The SI pin accepts data into the input shift register on the falling edge of the SCLK signal, while the SO pin shifts data information out of the SO line driver on the rising edge of the SCLK signal. It is important that 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 a passive pull-down, RDWN. When CSB is logic [1], signals at the SCLK and SI pins are ignored, and SO is tri-stated (high-impedance) (see Figure 8).

Single 16-Bit Word SPI Communication SERIAL INPUT (SI) CHIP SELECT (CS) The SI pin is a serial interface 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 to D0. SI has a passive pull-down, RDOWN. The CSB pin enables communication with the master device. When this pin is in a logic [0] state, the device is capable of transferring information to, and receiving information from, the master device. The 06XS3517 device 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 a passive pull-up, RUP. 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, and the state of the key inputs. The SO pin changes state on the rising edge of SCLK and reads out on the falling edge of SCLK. MC06XS3517 22 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DEVICE OPERATION OPERATION MODES FUNCTIONAL DEVICE OPERATION OPERATION MODES SLEEP MODE The Sleep mode is the default mode of the 06XS3517. This is the state of the device after first applying battery voltage (VBAT) and prior to any I/O transitions. This is also the state of the device when IGN, FOG, FLASHER, and RSTB are logic [0] (wake = 0). In the Sleep mode, the outputs and all internal circuitry are OFF to minimize current draw. In addition, all SPI-configurable features of the device are reset. The 06XS3517 will transit to two modes (Normal and Fail) depending on wake and fail signals (see Fig13). The transition to the other modes is according following signals: • Wake = IGN or IGN_ON or FLASHER or FLASHER_ON or RSTB or FOG or FOG_ON • Fail = VCC fail or SPI fail or External limp NORMAL MODE The 06XS3517 is in Normal mode when: • Wake = 1 • Fail = 0 In Normal operating mode the power outputs are under full control of the SPI as follows: • The outputs 1 to 6, including multiphase timing and selectable slew-rate, are controlled by the programmable PWM module. • The outputs 1 to 5 are switched OFF in case of an undervoltage on VBAT. • The outputs 1 to 5 are protected by the selectable overcurrent double window and overtemperature shutdown circuit. • The digital diagnosis feature transfers status of the smart outputs via the SPI. • The analog current sense output (current recopy feature) can be routed by the SPI. • The outputs 1 and 5 can be configured to control LED loads. • The SPI reports NM = 1 in this mode. The figure below describes the PWM, outputs and overcurrent behavior in Normal mode. D7 bit D0-D6 bits Output Overcurrent FAIL MODE The 06XS3517 is in Fail mode when: • Wake = 1 • Fail = 1 In Fail mode: • The outputs are under control of external pins (see Table 7) • The outputs are fully protected in case of an overload, overtemperature and undervoltage (on VBAT or on VCC). • The SPI reports continuously the content of address 11 (Initialization register), regardless previously requested output data word. • Analog current sense is not available. • Output 2 is configured in Xenon mode. • In case of an overload (OCHI2 or OCLO) conditions or undervoltage on VBAT, the outputs are under control of autorestart feature. • In case of serious overload condition (OCHI1 or OT) the corresponding output is latched OFF until a new wakeup event (wake = 0 then 1).

The autorestart circuitry is used to supervise the outputs and reactivate high-side switches in cases of overload or undervoltage failure conditions, to provide a high availability of the outputs. Autorestart feature is available in Fail mode (after loss of SPI communication). Autorestart is activated in case of overload condition (OCHI2 or OCLO) or undervoltage condition on VBAT (see Figure 12). The autorestart periodically switches ON the outputs. During ON state of the switch OCHI1 window is enabled for tochi_Auto, then after the output is protected by OCLO. Output current OCHI1 OCLO or UV fault Auto period To leave Fail mode, the fail condition must be removed (fail =0). The microcontroller has to toggle the SPI D10 bit (0 to 1) to reset the watchdog bit (WD); the other bits are not considered. The previous latched faults are reset by the transition into Normal mode. TRANSITION NORMAL TO FAIL MODE To leave the Normal mode, a fail condition must occur (fail = 1). The previous latched faults are reset by the transition into Fail mode. If the SI is shorted to VDD, the device transmits to Fail Safe mode until the WD bit toggles through the SPI (from [0] to [1]). All settings are according to predefined values (all bits set to logic [0]). START-UP SEQUENCE OCLO tochi_auto TRANSITION FAIL TO NORMAL MODE time Figure 9. Overcurrent window in case of Autorestart In case of OCHI1 or OT, the channel is latched OFF until wake-up (wake = 0 then 1). In case of OCLO or undervoltage, the output is switched OFF and turned On again automatically after the autorestart period (150 ms for 6.0 mOhm channels or 75 ms for 17 mOhm channels). In case of an undervoltage in Fail mode, the outputs 1 to 5 will be latched off. The corresponding output is switched on only after the autorestart period (tAUTORST-T1 or tAUTORST-T2). The 06XS3517 enters in Normal mode after start-up if following sequence is provided: • VBAT and VCC power supplies must be above their undervoltage thresholds (Sleep mode). • generate wake up event (wake = 1) from 0 to 1 on RSTB. The device switches to Normal mode. • apply PWM clock after maximum 200 μs (min 50 μs). • send SPI command to the Device status register to clear the clock fail flag to enable the PWM module to start. Figure 10 describes the wake-up block diagram. POWER OFF MODE The 06XS3517 is in Power OFF mode when the battery voltage is below VBATPOR[1,2] thresholds. For more details, refer to Loss of VBAT.

Wake-up Block Diagram MC06XS3517 26 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DEVICE OPERATION LOGIC COMMANDS AND REGISTERS LOGIC COMMANDS AND REGISTERS SERIAL INPUT COMMUNICATION SPI communication compliant to 3.3 V and 5.0 V is accomplished using 16-bit messages. A message is transmitted by the master starting with the MSB, D15, and ending with the LSB, D0. Each incoming command message on the SI pin can be interpreted using the bit assignment described in Table 8. The 5 bits D15 : D11, called register address bits, are used to select the command register. Bit D10 is the watchdog bit. The remaining 10 bits, D9 : D0, are used to configure and control the output and its 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. All SPI registers are reset (all bit equal 0) in case of RSTB equal 0 or fail mode (Fail=1). Table 8.

The register bits D1 and D0 determine the content of the 16 bits of the next SO data. (Refer Serial Output Communication (Device Status Return Data)) Table describes the register of initialization. The watchdog timeout is specified by t WDTO parameter. As long as the WD bit (D10) of an incoming SPI message is toggled within the minimum watchdog timeout period (WDTO), the device will operate normally. If an internal watchdog timeout occurs before the WD bit is toggled, the device will revert to Fail mode. All registers are cleared. To exit the Fail mode, send valid SPI communication with WD bit = 1. Table 10.

When bit D0 is set to logic [1], the open load detection circuit for LED is activated for output 1. When bit D0 is set to logic [0], open load detection circuit for standard bulbs is activated for output 1. When bit D5 is set to logic [1], the LED Control is activated for output 1. The Configuration Current Sense register is used to disable the high overcurrent shutdown phase (OCHI1 and OCHI2 dynamic levels) in order to activate immediately the current sense analog feedback. When bit D9 is set to logic [1], the current sense synchronization signal is reported on FETOUT output pin. When the corresponding NO_OCHI bit is set to logic [1], the output is only protected with OCLO level. The current sense is immediately available if it is selected through the SPI, as described in Figures 13. The NO_OCHI bit per output is automatically reset at each corresponding ON/OFF bit transition from logic [1] to [0], and in case of overtemperature or overcurrent fault. All NO_OCHI bits are also reset in case of undervoltage fault detection. ADDRESS 00010 — CONFIGURATION PRESCALER AND SR Two configuration registers are available at this address. The Configuration Prescaler when D9 bit is set to logic [0] and Configuration SR when D9 bit is set to logic [1]. The Configuration Prescaler register is used to enable the PWM clock prescaler per output. When the corresponding PR bit is set to logic [1], the clock prescaler (reference clock divided by 2) is activated for the dedicated output. The SR Prescaler register is used to increase the output slew rate by a factor of 2. When the corresponding SR bit is set to logic [1], the output switching time is divided by 2 for the dedicated output. ADDRESS 01001 — CONTROL OUT1 Bits D9 and D8 control the switching phases as shown in Table 11. Table 11.

OUT1 is turned OFF with bit D7 at logic [0]. This register allows the master to control the duty cycle and the switching phases of OUT1. The duty cycle resolution is given by bits D6 : D0. D7 = 0, D6 : D0 = XX output OFF. D7 = 1, D6 : D0 = 00 output ON during 1/128. D7 = 1, D6 : D0 = 1A output ON during 27/128 on PWM period. D7 = 1, D6 : D0 = 7F output continuous ON (no PWM). ADDRESS 01010 — CONTROL OUT2 Same description as OUT1. ADDRESS 01011 — CONTROL OUT3 Same description as OUT1. ADDRESS 01100 — CONTROL OUT4 Same description as OUT1. ADDRESS 01101 — CONTROL OUT5 Same description as OUT1. ADDRESS 01110 — CONTROL EXTERNAL SWITCH new message data is clocked into the SI pin. The first 16 bits of data clocking out of the SO, and following a CSB transition, is dependant upon the previously written SPI word (SOA1 and SOA0 defined in the last SPI initialization word). Any bits clocked out of the SO pin after the first 16 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. A valid message length is determined following a CSB transition of logic [0] to logic [1]. If the message length is valid, 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. The output status register correctly reflects the status of the Initialization-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 exceptions: • 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. • Battery transients below 6.0 V, resulting in an undervoltage shutdown of the outputs, may result in incorrect data loaded into the status register. Same description as OUT1. SERIAL OUTPUT BIT ASSIGNMENT ADDRESS 01111 — TEST MODE The contents of bits OD15 : OD0 depend on bits D1: D0 from the most recent initialization command SOA[1:0] (refer to Table 9), and as explained in the paragraphs that follow. The register bits are reset by a read operation and also if the fault is removed. Table 12 summarizes the SO register content. Bit OD10 reflects Normal mode (NM). This register is reserved for test and is not available with the SPI during normal operation. 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 first as the Table 12.

Logic [1] indicates the OUT1 voltage is higher than VOUT_TH PROTECTION AND DIAGNOSIS FEATURES OUTPUT PROTECTION FEATURES The 06XS3517 provides the following protection features: • Protection against transients on VBAT supply line (per ISO 7637) • Active clamp, including protection against negative transients on output line • Overtemperature • Severe and resistive overcurrent • Open Load during ON state These protections are provided for each output (OUT1:5). Output current OCHI1 OCHI2 OCLO Overtemperature Detection The 06XS3517 provides overtemperature shutdown for each output (OUT1:OUT5 ). It can occur when the output pin is in the ON or OFF state. An overtemperature fault condition results in turning OFF the corresponding output. The fault is latched and reported via the SPI. To delatch the fault and be able to turn ON again the outputs, the failure condition must be removed (T< 175 °C, typically) and: • if the device was in Normal mode, the output corresponding register (bit D7) must be rewritten. Application of complete OCHI window (OCHI1+OCHI2 during t2) depends on toggling or not toggling the D7 bit. • if the device was in Fail mode, the corresponding output is locked until restart of the device: wake-up from Sleep mode or VBATPOR1. The corresponding SPI fault report (OTS bit) is removed after a read operation. Overcurrent Detections The 06XS3517 provides a dynamic overcurrent shutdown protection (see Figure 12) in order to protect the internal power transistors and the harness in the event of overload (fuse characteristic). t1 t2 time Figure 12. Two-segment Overcurrent Window in Normal Mode OCHI (IOCHI1 and then IOCHI2) is only activated after toggling D7 bit of the corresponding Control Out registers in Normal Mode. During switch-on, a severe short-circuit condition at the output is reported as an OCHI fault. In Fail Mode, the control of OCHI window is provided by the toggles: IGN_ON, Flasher_ON, and FOG_ON. The current thresholds (IOCHI1, IOCHI2 and IOCLO) and the time (t1 and t2) are fixed numbers for each channel. After t2, the OCLO current threshold is activated to protect in steady state. t1 and t2 times are compared to “on” state duration (tON) of the output. In case of the output is controlled in PWM mode during the inrush period, the tON corresponds to the sum of each “ON” state duration in order to only account for times the channel was actually in the ON state. OUT2 is default loaded with the Xenon profile. The use of H7 bulbs at this output requires SPI programming (Xenon bit). In case of overload (OCHI1 or OCHI2 or OCLO detection), the corresponding output is disabled immediately. The fault is MC06XS3517 Analog Integrated Circuit Device Data Freescale Semiconductor 31 FUNCTIONAL DEVICE OPERATION PROTECTION AND DIAGNOSIS FEATURES latched and the status is reported via the SPI. To delatch the fault, the failure condition must be removed and: For OCHI1: • if the device was in Normal mode: the channel’s associated on/off bit (bit D7) must be rewritten D7=1. Application of complete OCHI window depends on toggling or not toggling D7 bit. • if the device was in Fail mode, the failure is locked until restart of the device: wake-up from Sleep mode or VBATPOR1. For OCHI2 and OCLO: • if the device was in Normal mode: channel’s associated on/off bit (bit D7) must be rewritten D7=1. Application of complete OCHI window depends on toggling or not toggling D7 bit. • if the device was in Fail mode, Autorestart is activated. The device Autorestart feature opens a fixed window width and restarts at a fixed period with OCHI1 window. Autorestart feature resets OCHI2 or OCLO fault after corresponding Autorestart period. The SPI fault reports are removed together after a read operation: - OC bit=(OCHI1) or (OCHI2) fault - OVL bit=(OCHI1) or (OCHI2) or (OCLO) fault Overvoltage detection and active clamp The 06XS3517 possesses an active gate clamp circuit in order to limit the maximum drain to source voltage. In case of overload on an output the corresponding switch (OUT[1 to 5]) is turned off which leads to high-voltage at VBAT with an inductive VBAT line. The maximum VBAT voltage is limited at VBATCLAMP by automatically turning on the channel. In case of open load condition, the positive transient pulses (ISO 7637 pulse 2 and inductive battery line) shall also be handled by the application. Figures 13 and 14 describe the faults management in Normal mode and Fail mode. Note: t1 and t2 refer to Figure 12.

Figure 14. Faults Management in Fail Mode (for OUT[1:5] Only) DIAGNOSTIC Functions Open Load The 06XS3517 provides open load detection for each output (OUT1:OUT5 ) when the output pin is in the ON state. Open load detection levels can be chosen by the SPI to detect a standard bulb, a Xenon bulb for OUT2 only, or LEDs (OLLED bit). Open load for LEDs only is detected during each regular switch-off state or 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. When an open load has been detected, the output stays ON. To delatch the fault bit, the condition should be removed and the SPI read operation is needed (OL bit). In case of a Power on Reset on VBAT, the fault will be reset. Current Sense The 06XS3517 diagnosis for load current (OUT1:6) is done using the current sense (CSNS) pin connected to an external resistor. The CSNS resistance value is defined in function to VCC voltage value. It is recommended to use resistor 500 Ohm < RCSNS < 5.0 kOhm. Typical value is 1.0 kOhm for 5.0 V application. The channel the current of which is sensed is addressed through bits MUX[4,2] bits of the Initialization register. The current recopy feature for OUT1:5 is disabled during a high overcurrent shutdown phase (t2) and is only enabled during low overcurrent shutdown thresholds. The current recopy output delivers current only during ON time of the output switch without overshoot (aperiodic settling). The current recopy is not active in Fail mode. With a calibration strategy, the output current sensing precision can be improved significantly. One calibration point at 25 °C for 50% of FSR allows removing part to part contribution. So, the calibrated part precision goes down to ±6.0% over [20% - 75%] output current FSR, overvoltage range (10 V to 16 V) and temperature range (-40 to 125 °C). MC06XS3517 Analog Integrated Circuit Device Data Freescale Semiconductor 33 FUNCTIONAL DEVICE OPERATION PROTECTION AND DIAGNOSIS FEATURES Board Temperature Feedback TEMPERATURE PREWARNING The 06XS3517 provides a voltage proportional to the temperature on the GND flag, often representative for the temperature of the underlaying PCB land. This voltage is available at the CSNS output pin when the associated UX[2,0] bits are set to “111”. Figure 15 shows the output voltage over temperature. The 06XS3517 provides a temperature prewarning reported via the SPI (OTW bit) in Normal mode. The information is latched. To delatch, a read SPI command is needed. In case of a Power on Reset, the fault will be reset. . The 06XS3517 provides the status of the FLASHER, FOG, and IGN pins via the SPI in real time and in Normal mode. typ 2.5 FAILURE HANDLING STRATEGY min max A highly sophisticated fault handling strategy allows guaranteeing the various lighting functions even in case of failures inside the component or the light module.

So, one calibration point at 25 °C allows removing part to part contribution, as presented in Figure 16. typ 2.5 min max REVERSE POLARITY PROTECTION ON VBAT In case of a permanently reverse voltage operation, the channels are turned ON (RSD Ohm) in order to prevent thermal overloads. No protections are available. An external diode on VCC is necessary in order to protect the 06XS3517 in cases from reverse polarity. In case of negative transients on the VBAT line (per ISO 7637), the VCC supplied functions are still available operating, while the VBAT line is negative. Without loads on OUT1:5 pin, an external clamp between VBAT and GND is mandatory to avoid exceeding maximum ratings. The maximum external clamp voltage shall be between the reverse battery condition and -20 V. Therefore, the device is protected against latch-up with or without load on OUT outputs.

Analog Temperature Precision with Calibration Strategy Output Voltage Status The 06XS3517 provides the state of OUT1:OUT5 outputs in real time through the SPI. The OUT bit is set to logic [1] when the corresponding output voltage is higher or equal then half of the supply voltage. This bit allows synchronizing current sense and diagnosing short-circuit between OUT and VBAT terminals. During an undervoltage of VBAT (VBATPOR1 < VBAT < VBATUV), the outputs [1 - 5] are switched off immediately. No current path from VBAT to VCC exists. The external MOSFET (OUT6) can be controlled in Normal mode by the SPI if VCC is above VCCUV. The fault is reported to the UVF bit (OD13). To delatch the fault, the undervoltage condition should be removed and: • To turn-on the output, the corresponding D7 bit must be rewritten to logic [1] in Normal mode. Application of the OCHI window depends on toggling or not toggling the D7 bit. • If the device was in Fail mode, the fault will be delatched by the Autorestart feature periodically. MC06XS3517 34 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DEVICE OPERATION PROTECTION AND DIAGNOSIS FEATURES In case of VBAT < VBATPOR1 (Power OFF mode), the behavior depends on VCC: • all latched faults are reset if VCC < VCCUV, • all latched faults are maintained under VCC in nominal conditions. In case VBAT is disconnected, OUT[1:5] outputs are OFF. OUT6 output state depends on the previous SPI configuration. The SPI configuration, reporting, and daisy-chain features are provided for RST is set to logic [1]. The SPI pull-up and pull-down current resistors are available. This fault condition can be diagnosed with UVF fault in OD13 reporting bit. The previous device configuration is maintained. No current is conducted from VCC to VBAT. LOSS OF VCC (DIGITAL LOGIC SUPPLY LINE) LOSS OF GROUND (GND) During loss of ground, the 06XS3517 cannot drive the loads (the outputs (1:5) are switched OFF), but is not destroyed by the operating condition. Current limit resistors in the digital input lines protect the digital supply against excessive current (1.0 kOhm typical). The state of the external smart power switch controlled by FETOUT is not guaranteed, and the state of external smart MOS is defined with an external termination resistor. FATAL MISTREATMENT OF LOGIC I / O PINS The digital I / Os are protected against fatal mistreatment by signal plausibility check according to Table 17. Table 17. Logic I / O Plausibility Check During loss of VCC (VCC < VCCUV ) and with wake = 1, the 06XS3517 is switched automatically into Fail mode. The external smart MOSFET is turned OFF. All SPI registers are reset and must be reprogrammed when VCC goes above VCCUV. The device will transit in OFF mode if VBAT < VBATPOR2. LOSS OF VCC AND VBAT If the external VBAT and VCC supplies are disconnected (or not within specification: (VCC and VBAT) < VBATPOR1), all SPI register contents are reset with default values corresponding to all SPI bits are set to logic [0] and all latched faults are also reset.
