Product Summary

The RT9701PB 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 the RT9701PB is powered off. Its low quiescent current (23μA) and small package (SOT-23-5) is particularly suitable in battery-powered portable equipment. The applications of the RT9701PB include Battery-Powered Equipment, Motherboard USB Power Switch, USB Device Power Switch, Hot-Plug Power Supplies, and Battery-Charger Circuits.
