RT9715

90mΩ, 2A/1.5A/1.1A/0.7A High-Side Power Switches

with Flag

General Description

Features

^z90mΩ (typ.) N-MOSFET Switch

^zOperating Range : 2.7V to 5.5V

^zReverse Blocking Current

^zUnder Voltage Lockout

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.

^zDeglitched Fault Report (FLG)

^zThermal Protection with Foldback

^zOver Current Protection

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.

^zShort Circuit Protection

^zUL Approved−E219878

^zNemko Approved−NO49621

^zRoHS Compliant and Halogen Free

Applications

z USB Peripherals

z Notebook PCs
