Power Distribution Switches
General Description
The RT9701 is an integrated 100m
power switch
for self-powered and bus-powered Universal Series
Bus (USB) applications. A built-in charge pump is
used to drive the N-channel NMOSFET that is free
of parasitic body diode to eliminate any reversed
current flow across the switch when it is powered
off. Its low quiescent supply current (23
μ
A) and
small package (SOT-25) is particularly suitable in
battery-powered portable equipment.
Several protection functions include soft start to limit
inrush current during plug-in, current limiting at 1.5A
to meet USB power requirement, and thermal
shutdown to protect damage under over current
conditions.
