Function
Positive power supply voltage. Design the
wiring for the simultaneous max. short circuit
currents from channel 1 to 4 and also for low
thermal resistance
Input 1 .. 4, activates channel 1 .. 4 in case of
logic high signal
Output 1 .. 4, protected high-side power output
of channel 1 .. 4. Design the wiring for the
max. short circuit current
Diagnostic feedback 1/2 of channel 1 and
channel 2, open drain, low on failure
Diagnostic feedback 3/4 of channel 3 and
channel 4, open drain, low on failure
Ground 1/2 of chip 1 (channel 1 and channel 2)
Ground 3/4 of chip 2 (channel 3 and channel 4)
