General Description

The RT9715CA is a cost-effective, low-voltage, single

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

Low switch-on resistance (typ. 90m

Ω) and low supply

current (typ. 50

μA) are realized in this IC.

The RT9715CAintegrates 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

RT9715CA is an ideal solution for USB power supply and

can support in package SOT-23-5.
