onsemi NCP45760 load switch

The NCP45760 is a load management device, providing a component and area-reduced solution for efficient power domain switching with an inrush current limit via soft start.

This device is designed to integrate control and driver functionality with back-to-back high-performance low ON-resistance power MOSFETs in a single package. This cost-effective solution is ideal for reverse current applications and the specific power management and disconnect functions used in USB Type-C and Type-C Power Delivery (PD) ports.
