Description
The L9370 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.
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.
