General description

The NPS4069 is a 5.5 V, 55 mΩ load switch suitable

for applications up to 1.5 A.

The NPS4069 switch limits the output current to a

constant current by using a constant-current mode

when the output load exceeds the current limit

threshold or shorted. An internal voltage comparator

disables the load switch when the output voltage is

higher than the input to protect devices on the input

side of the switch. The FLG pin is an active low output

to indicate overcurrent, over temperature and reverse

voltage conditions.
