Advanced Load Management
Controlled Load Switch with Low RON
The NCP45541 load switch provides a component and area-
reducing solution for efficient power domain switching with inrush
current limit via softâstart. In addition to integrated control
functionality with ultra low onâresistance, this device offers system
monitoring via power good signaling. This cost effective solution is
ideal for power management and hot-swap applications requiring low
power consumption in a small footprint.
