Order this document by MC33143/D The MC33143 is a dual high–side switch designed for solenoid control in harsh automotive applications, but is well suited for other environments. The device can also be used to control small motors and relays as well as solenoids. The MC33143 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power outputs. An internal charge pump is incorporated for efficient gate enhancement of the internal high–side power output devices. The outputs are designed to provide current to low impedance solenoids. The MC33143 provides individual output fault status reporting along with internal Overcurrent and Over Temperature protection. The device also has Overvoltage protection, with automatic recovery, which “globally” disables both outputs for the duration of an Overvoltage condition. Each output has individual Overcurrent and Over Temperature shutdown with automatic retry recovery. Outputs are enabled with a CMOS logic high signal applied to an input to providing true logic control. The outputs, when turned on, provide full supply (battery) voltage across the solenoid coil. The MC33143 is packaged in an economical 24 pin surface mount power package and specified over an operating voltage of 5.5 V ≤ VPwr < 26 V for –40°C ≤ TA ≤ 125°C. • Designed to Operate Over Wide Supply Voltages of 5.5 V to 26 V • • • • • • • • • • • • • DUAL HIGH–SIDE SWITCH SEMICONDUCTOR TECHNICAL DATA 24 1 Dual High–Side Outputs Clamped to –10 V for Driving Inductive Loads DW SUFFIX PLASTIC PACKAGE CASE 751E (SOP (16+4+4)L) Internal Charge Pump for Enhanced Gate Drive Interfaces Directly to a Microcontroller with Parallel Input Control Outputs Current Limited to 3.0 A to 6.0 A for Driving Incandescent Loads Chip Enable “Sleep Mode” for Power Conservation Individual Output Status Reporting PIN CONNECTIONS Fault Interrupt Output for System Interrupt Use Output ON or OFF Open Load Detection Overvoltage Detection and Shutdown Output Over Temperature Detection and Shutdown with Automatic Retry Sustained Current Limit or Immediate Overcurrent Shutdown Output Modes Output Short to Ground Detection and Shutdown with Automatic Retry Output Short to VPwr Detection SMARTMOS is a trademark of Motorola, Inc.

When an input is high, it’s corresponding output is active ON, and when low is disabled OFF. IN1 and IN2 have internal active pull–downs which allow a floating input pin to be conservatively interpreted as a logic low, turning Off the output. An unused input should be connected to ground. CEN Chip Enable (CEN) input pin, when low, disables both outputs (OUT1 and OUT2) and places the device in a “sleep mode” reducing the bias current required from VDD and VPwr. A falling edge of CEN causes OUT1 and OUT2 to rapidly turn OFF. A falling edge of CEN should precede any VDD shutdown to allow time OUT1 and OUT2 to be disabled. When CEN is low, INTerrupt (INT) and STATus 1 and 2 (STAT1–2) will be tri–stated (high impedance). The CEN pin can also be used for power–on reset and under voltage lockout to disable the outputs for power supply voltages less than 4.5 V. CEN is a dependent input from the system microcontroller unit (MCU) or some other integrated circuit. It has an internal pull–up resistor to VDD affording a floating pin to be interpreted as a logic high. Rpull–up is greater than 50 kΩ. If used externally, this pin should be connected to VDD. STAT1. STAT2 The STATus pins (STAT1–2) respectively indicate the presence of faults on OUT1–2. STAT1–2 will be logic high during normal operation. A logic low will occur whenever an Open Load, Short–to–Ground, Short–to–Supply (Battery), Thermal Limit, or Overvoltage Shutdown fault condition is experienced on a corresponding output. STAT1–2 are both active low digital drivers. A 10 kΩ resistor between STAT1–2 and the system CPU may improve a Failure Mode Evaluation Analysis (FMEA) score if STAT1–2 are externally shorted to VPwr. If unused, this pin should be left connected. VPwr These pins are connected to the supply and provide load current to the DMOS outputs, are used pumping the DMOS gates, and for Overvoltage shutdown detection of the DMOS. The DMOS outputs will turn ON with 5.5 to 24 V applied to VPwr. VPwr is limited to –1.5 V for a maximum duration of 250 ms. A 10 nF de–coupling cap is recommended to be used from VPwr to Ground.

Ground continuity is required for the outputs2 to turn ON. 11 VDD This pin is to be connected to the 5.0 V logic supply of the system. A 10 nF de–coupling capacitor is recommended from VDD to Gnd. OUT1, OUT2 These pins are connected internally to the DMOS output transistors which source current into the corresponding load. Each output incorporates dynamic clamping to accommodate inductive loads. In addition, each output has independent short to ground detection and protection, current limit detection and protection, thermal limit detection and protection, ON open load and or short to supply (battery) detection. Neither output will turn ON if CEN is logic low. An unused output should be connected to a 10 kΩ load to prevent false fault reporting. A 1.0 nF filter capacitor may be used from OUT to Gnd to provide dV/dt noise filtering. 13, 24 MOTOROLA ANALOG IC DEVICE DATA 5 MC33143 PIN FUNCTION DESCRIPTION (continued) ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ Pin Symbol Description 14 SFPD This is a Short Fault Protect Disable (SFPD) input; which when logic high disables the internal current limit timer preventing OUT1–2 from latching OFF when confronted with an overcurrent condition. The condition of SFPD does not affect fault reporting. Current and thermal limit remain active when the SFPD pin is logic high. Having the SFPD pin logic high facilitates the device to drive incandescent lamp loads with peak in–rush currents in excess of three amperes. When SFPD is logic low, an overcurrent demand will latch OFF only the output affected. The device will then automatically begin active re–enabling of the corresponding output affected for the duration of the overcurrent condition. SFPD has an internal active pull–down which affords a floating input pin condition to be conservatively interpreted as a logic low. A 10 kΩ resistor between SFPD and the system CPU may improve the FMEA score if SFPD is externally shorted to OUT2. SFPD should be connected to Gnd or VDD for the desired operating mode and not be left “floating”. 15 GTST The Gate TeST (GTST) pin is used to stress the devices DMOS gates during testing operations. This pin should normally be connected to ground in the application. 23 INT The INTerrupt pin INT is active logic low and indicates the presence of a fault on either the output. INT can be paralleled with additional fault pins and used as a system CPU interrupt to indicate the presence of a fault. The system CPU can then read STAT1–2 to determine the specific type of fault occurring. INT will be logic high during normal operation. A logic low will result if a fault occurs on either OUT1 or OUT2. INT has an internal active pull–up and requires no external pull–up resistor to be used. The INT output has sufficient current drive capability to afford paralleling of up to five INT pins. A 10 kΩ resistor between INT and the system CPU may improve the FMEA score if INT is externally shorted to OUT1. This pin should be left unconnected if the feature is not used.

Open Load Output to VPwr Short Over Temperature VPwr Overvoltage “Sleep”/Under Voltage Mode, CEN Low 6 Output Condition STAT Condition MOTOROLA ANALOG IC DEVICE DATA MC33143 FUNCTIONAL DESCRIPTION General The MC33143 is designed as an interface device; between system’s electronic control unit and the actuators. It is designed to withstand several abnormal operating conditions, with the capability of reporting it’s operating status back to the control unit. The MC33143 will resume normal operation after having experienced 60 V transients on the VPwr line, output shorts to VPwr, open loads, output shorts to ground, over current, over temperature, or overvoltage conditions. Status information is available when ever a load experiences any of the faults. In addition, the MC33143 device incorporates internal output transient clamps allowing it to control inductive loads and survive negative voltage spikes without the need of external components. Power Supply Voltage Requirements The MC33143 is designed to operate with 5.5 V to 26 V applied to the power supply pin (VPwr) and 4.5 V to 5.5 V applied to the logic supply pin (VDD). If VPwr is above the specified Overvoltage Shutdown voltage limit (VPwr(ovsd)) the outputs will be disabled and the status line voltage will transition to a low logic state indicating a fault. When the CEN voltage is at a low logic state, OUT1 and OUT2 will turn OFF. This provides an under voltage shutdown for VPwr in the 0 to 4.5 V range. The active low under voltage must be externally provided to the CEN pin. The MC33143 is designed to survive the loss of VPwr. Normal Operations The MC33143 is considered to be operating normal when the following conditions are met: 1) 5.5 V ≤ VPwr ≤ 26 V. 2) –40°C ≤ TJ ≤ 150°C. 3) When load currents (IO) exceed the Output Open “ON” detection current (IO(on)) and occur within the Open Sense “ON” time (tos(on)) window. 4) When load currents (IO) are less than the Output Limit Current (IO(Lim)) for durations in excess of the Short Sense time (tss). 5) So long as the output of the device is able to clamp negative voltages produced when switching inductive loads to the specified clamp voltage (VClamp). Fault Conditions Anytime the MC33143 is not operating normal it is said to be operating in a “faulted condition”. Fault conditions will result in level changes of the status outputs (STAT1–2) and disable the affected faulted output. Output Over Current/Short to Ground Faults For an enabled input, the status line voltage will transition to a low logic level if the output current equals or exceeds the Output Limit current (IO(Lim)) for a period of time in excess of the Short Sense time (tss). Only the affected output will turn off; independent of the corresponding input’s condition. The device incorporates an internal short duration Refresh timer MOTOROLA ANALOG IC DEVICE DATA (tref) to mask edge transients due to switching noise. The output will remain off for the short tref duration and then attempt to re–energize the shorted load. The internal protection circuitry continues to be active during this process. If the short is not removed; the circuitry will sequence and the output will remain off for a another tref time. This process will continue so long as the output remains shorted and the input remains in a logic high state. If the short is removed from the output, while the input is ON, the MC33143 will return to normal operation and the status line will go to a logic high state after the tref time–out. The status line will also go to a logic high state on the falling edge of the corresponding input. Open Load/Short to VPwr Fault This condition is commonly referred to as an “ON” open fault. For this fault to be present, the output current of the driver must be at or near zero. Since the MC33143 is a “high–side switch”; It is for this reason a Short to VPwr fault resembles an Open Load fault, in so far as the MC33143 is concerned. When this fault is present the status line voltage will transition to a low logic level so long as the output current does not exceed the specified Open ON detection current (IO(on)) for a duration in excess of the specified Open Sense ON time (tos(on)). If the open load or output short to VPwr condition is removed, and the corresponding input is at a logic high state, the status line voltage will go to a logic high state after the drain current has exceeded IO(on). The ON open fault detection circuit incorporates a voltage comparator which monitors the voltage difference from VPwr to OUT. When ever the VPwr to OUT voltage difference falls below 10 mV an ON Open fault is reported. A Short to VPwr external to any module the MC33143 is in will not be detected as an ON Open fault if the voltage difference from VPwr to OUT is greater than 10 mV. VPwr line voltage drops directly impact this detection ability. Overvoltage Fault When this fault is present the status line voltage will transition to a logic low state when VPwr exceeds the specified Overvoltage Shutdown threshold VPwr(ovsd). This fault produces a “global” response on the part of the MC33143 by turning OFF both outputs independent of input conditions. The outputs will resume normal operation when VPwr drops the specified Overvoltage Hysteresis VPwr(hys) value. Over Temperature Fault When this fault is present the status line voltage transitions to a low logic level when the junction temperature of either output exceeds the specified Thermal Limit threshold (TLim). Only the specific faulted output will shutdown independent of the input condition. The other output will continue to operate in a normal fashion unless it also becomes faulted. The thermally faulted output will resume normal operation when the junction temperature drops the specified Over Temperature Shutdown Hysteresis (TLim(hys)) amount. 7 MC33143 OUTLINE DIMENSIONS DW SUFFIX PLASTIC PACKAGE CASE 751E–04 (SOP (16+4+4)L) ISSUE E –A– 24 NOTES: 1.
