NPS40 Load Switch

            NPS40 Load Switch
                    Nexperia's NPS40 5.5 V, 55 mOhm load switch has precision adjustable current limit
    

Nexperia's load switch ICs are non-discrete electronic switches used for power management to control a power supply by turning on and off a power rail to a load. It can reduce power consumption by turning off unused loads, providing power sequencing, inrush current control, overcurrent limitation, short circuit protection, overtemperature protection, and active reverse current blocking. Nexperia load switches are suitable for a large range of industrial, consumer, computing, and automotive applications.
