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 on failure
