RT9728 - Richtek

RT9728 1.3A Power Switch

The RT9728 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 RT9728 offers a programmable current limit threshold between 75mA and 1.3A (typ.) via an external resistor. .
