L9369-TR ASIL-D Automotive EPB/ESP Dual H-Bridge Pre-Driver
The L9369-TR is an automotive-grade multifunctional pre-driver IC engineered by STMicroelectronics exclusively for electronic parking brake (EPB) and electronic stability program (ESP/ESC) systems, encapsulated in a 64-pin 10×10mm LQFP surface-mount package with tape-and-reel supply, fully AEC-Q100 qualified and certified to ISO 26262 ASIL-D highest functional safety level for braking applications. This integrated device features dual H-bridge pre-driver stages designed to gate eight external power MOSFETs (four high-side plus four low-side switches) to independently control left and right rear brake motors, while embedding high-precision analog sensing channels, comprehensive diagnostic logic and multi-layer fault protection circuits in a single compact chip. Optimized for 12V vehicle battery platforms, it consolidates motor drive control, real-time electrical signal acquisition and safety monitoring to simplify system architecture for critical vehicle braking actuators with strict reliability standards.
It acts as the core actuator control semiconductor for automotive EPB electronic parking brake rear motor drive units, ESP/ESC hydraulic and brake torque modulation actuators, rear wheel brake force regulation subsystems, and light commercial vehicle stability control modules, serving safety-critical braking hardware where zero-tolerance fault handling, precise motor torque control and certified ASIL-D functional safety compliance are mandatory regulatory and performance requirements for road-legal vehicle production.
