The RT9701B 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-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.
