Advanced Load Management

The NCP4545 load switch provides a component and area-reducing

solution for efficient power domain switching with inrush current

limit via soft start. It is designed to integrate control and driver

functionality with a high performance low on-resistance power

MOSFET in a single device. This cost effective solution is ideal for

power management and hot−swap applications requiring low power

consumption in a small footprint.
