Overview

® RT9728C 120mΩ, 1.
3A Power Switch with Programmable Current Limit General Description 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 offers a programmable current limit threshold between 75mA and 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 pre...
