RT9728B

120mΩ, 1.8A Power Switch with Adjustable Current Limit

General Description

Features



10% Current Limit Accuracy @ 1.3A

The RT9728B is a cost effective, low voltage, single

P-MOSFET power switch IC for USB application with a

adjustable current limit feature. Low switch-on resistance

(typ. 120mΩ) and low supply current (typ. 120μA) are

realized in this IC. The RT9728B can offer a adjustable

current limit threshold between 75mA and 1.8A (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 due to

high inrush current. The RT9728B is an ideal solution for

USB power supplies and can support flexible applications

since it is suitable for various current limit requirements.

It is available in the SOT-23-6 and WDFN-6L2x2 packages.

^Adjustable Current Limit : 75mA to 1.8A (typ.)
