The L9369-TR targets the specific application of electric parking braking, suitable for system configuration in cable-puller or Motor Gear Unit (MGU).

 

The cores are two H-bridge driver stages to drive 8 external FETs for the rear wheels brakes actuators. The stages are fully driven and configurable via SPI, also in PWM control mode and protected against overcurrent, with drainsource and gate-source voltages monitoring.

 

The set of the interfaces is completed by 4 GPIO (General Purpose I/O) pins and a button interface allows to manage specific customer requirements from Electronic parking braking (EPB) button console both in Normal and Sleep Mode.
