NEXPERIA NPS4053 high density Integrated Circuit (IC) provides a smaller footprint and enhanced system protection to help increase system reliability and ensure safety. Device is commonly positioned closest to the load for power sequencing and inrush-current control, and shutting off power islands to conserve power, making it especially valuable in battery-operated equipment. The monolithic solution simplifies circuit design and has an 85% smaller pcb footprint than a comparable network of discrete components. Product operates with an input voltage of 2.5V-5.5V and contains a 55mΩ self-protected MOSFET, which efficiently manages the flow of power to the load. Device includes programmable current-limiting circuitry allowing precise control of the load current over a range of 110mA to 2.5A with an accuracy of +6%.
