  • The L9369 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.
    Two configurable HS/LS stages are present with programmable output voltage to drive LED arrays, with feedforward regulation.
    2 Motor Speed Sensor interfaces (MSS) are available to acquire position feedback from brake actuators (shared with Lamp driver stage and GPIO).
    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.
