Advanced Load Management

The NCP4552x series of load switches provide a component and

area-reducing solution for efficient power domain switching with

inrush current limit via soft start. In addition to integrated control

functionality with ultra low on−resistance, these devices offer system

safeguards and monitoring via fault protection and power good

signaling. This cost effective solution is ideal for power management

and hot-swap applications requiring low power consumption in a

small footprint.
