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
