RT9715AGB Overview

Operating Range : 2.7V to 5.5V, Reverse Blocking Current

RT9715
90mΩ, 2A/1.5A/1.1A/0.7A High-Side Power Switches
Ω
with Flag
General Description
The RT9715 is a cost-effective, low-voltage, single
N-MOSFET high-side Power Switch IC for USB application.
Low switch-on resistance (typ. 90mΩ) and low supply
current (typ. 50uA) are realized in this IC.
The RT9715 integrates an over-current protection circuit,
a short fold back circuit, a thermal shutdown circuit and an
under-voltage lockout circuit for overall protection. Besides,
a flag output is available to indicate fault conditions to the
local USB controller. Furthermore, the chip also integrates
an embedded delay function to prevent miss-operation from
happening due to inrush-current. The RT9715 is an ideal
solution for USB power supply and can support flexible
applications since it is available in various packages such
as SOT-23-5, SOP-8, MSOP-8 and WDFN-8L 3x3.
