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. These devices are designed to
integrate control and driver functionality with a high performance low
on−resistance power MOSFET in a single package. This cost effective
solution is ideal for power management and hot-swap applications
requiring low power consumption in a small footprint.
