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
