RT9728AHGQW Product Details

The RT9728AHGQW 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 RT9728AHGQW can offer 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. 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 mis-operation from happening due to high inrush current. The RT9728AHGQW 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 WDFN-6L 2x2 package.
