Function
Positive power supply voltage. Design the
wiring for the simultaneous max. short circuit
currents from channel 1 to 2 and also for low
thermal resistance
Input 1,2, activates channel 1,2 in case of
logic high signal
Output 1,2, protected high-side power output
of channel 1,2. Design the wiring for the max.
short circuit current
Diagnostic feedback 1,2 of channel 1,2,
open drain, low in on state on failure or high in
off state on failure
