RT9741

100mΩ, 1.5A/0.7A High-Side Power Switches

General Description

Features

^100mΩ (typ.) N-MOSFET Switch

^Operating Range : 2.7V to 5.5V

^Reverse Blocking Current

The RT9741 is a cost-effective, low-voltage, single N-

MOSFET high-side Power Switch IC for USB application.

Low switch-on resistance (typ. 100mΩ) and low supply

current (typ. 50μA) are realized in this IC.

^Under-Voltage Lockout

^Thermal Protection with Foldback

^Over-Current Protection

The RT9741 integrates an over-current protection circuit,

a short fold back circuit, a thermal shutdown circuit and

an under-voltage lockout circuit for overall protection.

Furthermore, the chip also integrates an embedded delay

function to prevent miss-operation from happening due to

inrush-current. The RT9741 is an ideal solution for USB

power supply and can support flexible applications since

it is available in the SOT-23-3 package.

^Short-Circuit Protection

^RoHS Compliant and Halogen Free

Applications

 USB Peripherals

 Notebook PCs
