Advanced Load Management
Controlled Load Switch with Low RON
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 onâresistance, 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.
