Advanced Load Management
Controlled Load Switch with Low R_ON
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.
