RT9701
100mΩ Power Distribution Switches
General Description
The RT9701 is an integrated 100mΩ 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 MOSFET that is free of parasitic
body diode to eliminate any reversed current flow across
the switch when it is powered off. Its low quiescent current
(23uA) and small package (SOT-23-5) 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.
