Description
The device has integrated several functions which
save job load of the microcontroller and save
necessary connections to the microcontroller. It’s
possible to connect analog and digital high side
drivers (HSD) to the device and control them via
SPI interface. A synchronous detailed diagnostics
feature is integrated.
The device has 8 outputs to the HSD with the
possibility to be driven either by steady state
ON/OFF mode or by PWM. Two clock inputs used
as base frequency to generate the PWM signal
internally are provided. The outputs are fully
independent and can also be driven with phase
shift to improve characteristics of power net
during the inrush phase. The device has 8 current
sense (CS)/status (ST) pins connected to the
HSD to run diagnostics. The index of ST/CS pin
corresponds to the input connected to the same
HSD channel (ST0/CS0 with OUT0, ST1/CS1
with OUT1 …).

EN
With this pin pulled high, the device leaves low power mode. An internal pull down resistor
guarantees the OFF condition when not connected.
