L9369-TR

L9369-TR is an automotive IC for a specific application of electric parking braking. This 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 drain source and gate-source voltages monitoring. A synchronized motor voltages and currents acquisition, is performed via full differential amplifiers with programmable and precise gain and low offset and 10 ADC sigma-delta modulators. The set of the interfaces is completed by 4 GPIO pins and a button interface allows to manage specific customer requirements from electronic parking braking (EPB) button console both in normal and sleep mode.
