Controlled Load Switch with Low RON
NCP45732
The NCP45732 load management devices provide a component and
area−reducing solution for efficient power domain switching with
inrush current limit via soft start. These devices are designed to
integrate control and driver functionality with a high performance low
on−resistance power MOSFET in a single package offering safeguards
and monitoring via fault protection and power−good signaling. This
cost effective solution is ideal for power management and disconnect
functions in USB Type−C ports and power management applications
requiring low power consumption in a small footprint.
