onsemi NCP45610/NCP45650/51 ecoSwitch™ Load Switches

onsemi NCP45610/NCP45650/51 ecoSwitch™ Load Switches are load management devices that deliver a component and area-reducing solution for efficient power domain switching with inrush current limit via soft start.

The onsemi NCP45610/NCP45650/51 are designed to integrate control and driver functionality with a high-performance, low on-resistance power MOSFET in a single package. The NCP45610 additionally offers safeguards and monitoring via fault protection and power-good signaling.

The switch’s cost-effective solution is intended for power management and disconnect functions in USB ports requiring low power consumption in a small footprint.
