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 drainsource 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.
