NPS4053 5.5 V Load Switch

Nexperia's NPS4053 load switch with precision current limit offers active reverse voltage protection and built-in soft start

Image of Nexperia's NPS4053 5.5 V Load SwitchNexperia's NPS4053 switch limits the output current to a constant current using a constant-current mode when the output load exceeds the current limit threshold or is 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, overtemperature, and reverse voltage conditions.
