RT9728C

120mΩ, 1.3A Power Switch with Programmable Current Limit

General Description

Features



10% Current Limit Accuracy @ 1.3A

The RT9728C is a cost effective, low voltage, single

P-MOSFET high-side power switch IC for USB application

with a programmable current limit feature. Low switch-on

resistance (typ.120mΩ) and low supply current (typ.

120μA) are realized in this IC.The RT9728C can offer a

programmable current limit threshold between 75mAand

1.3A(typ.) via an external resistor. The 10% current limit

accuracy can be realized for all current limit settings. In

addition, 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

mis-operation from happening due to high inrush current.

The RT9728C is an ideal solution for USB power supply

and can support flexible applications since it is functional

for various current limit requirements. It is available in

SOT-23-6 and WDFN-6L 2x2 packages.

^Adjustable Current Limit : 75mA to 1.3A (typ.)
