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 low on−resistance, 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.
