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. Both pins of each output have
to be connected in parallel for operation
according ths spec (e.g. k
). Design the wiring
for the max. short circuit current
Diagnostic feedback 1,2
of channel 1,2,
open drain, invers to input level
Ground 1
of chip 1 (channel 1)
Ground 2
of chip 2 (channel 2)
Sense current output 1,2;
proportional to the
load current, zero in the case of current
limitation of the load current
