General Description

The RT9742 is a cost-effective, low-voltage, single

N-MOSFET high-side Power Switch IC for USB application.

Low switch-on resistance and low supply current are

realized in this IC.

The RT9742 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

RT9742 is an ideal solution for USB power supply and

can support flexible applications since it is available in

TSOT-23-5, TSOT-23-5 (FC) and SOT-23-3 package.
