L9369-TR STMicroelectronics

L9369 Automotive IC for a specific application of electric parking braking Data brief 2 Motor Speed Sensors (MSS) interfaces to acquire speed information feedbacks via external Hall sensors. System wake-up in Sleep Mode Watchdog (configurable via SPI) LQFP64 (10x10x1.4mm) Description The L9369 targets the specific application of electric parking braking, suitable for system Features configuration in cable-puller or Motor Gear Unit (MGU). AEC-Q100 qualified The cores are two H-bridge driver stages to drive Functional safety concept for ISO26262 8 external FETs for the rear wheels brakes compliance actuators. The stages are fully driven and 4 High-side and Low-side gate pre-drivers for 8 configurable via SPI, also in PWM control mode external power NFETs and protected against overcurrent, with drain- Overcurrent protection with programmable source and gate-source voltages monitoring. thresholds A synchronized motor voltages and currents Programmable and NFET independent acquisition, is performed via full differential thresholds for VDS monitoring amplifiers with programmable and precise gain and low offset and 10 ADC sigma-delta 10 integrated Fully differential amplifiers with modulators. low offset, very precise gain, and self-test 10 separate ADC channels for digital Two configurable HS/LS stages are present with processing of motor current and voltage programmable output voltage to drive LED arrays, measurement with feedforward regulation. 32-bits - 10 MHz SPI with CRC for internal 2 Motor Speed Sensor interfaces (MSS) are setting, self-test and diagnostics available to acquire position feedback from brake actuators (shared with Lamp driver stage and Full drive of external power NFETs down to GPIO). 5.5 V battery input voltage Monitoring on Main power supply and The set of the interfaces is completed by 4 GPIO continuous BIST for internal regulators (General Purpose I/O) pins and a button interface allows to manage specific customer requirements Double Bandgap reference from Electronic parking braking (EPB) button 4 General Purpose I/O stages (GPIO) console both in Normal and Sleep Mode. Button Interface (9 configurable I/O pins) for monitoring and diagnostics in Normal and Table 1. Device summary Sleep Mode.
