The RT9722 is a cost effective, low voltage, single P-MOSFET high side power switch IC. Typical 145mΩ switch on resistance and 10μA quiescent current are realized in this IC. In order to fit different application, a SET pin is offered for current limit point setting, a resistor from SET to Ground sets the current limit for this switch.In addition, the RT9722 integrates a thermal shutdown circuit and under voltage lockout circuit for overall protection, and a FLAG output with delay is available to indicate fault conditions to the local controller. The RT9722 is an ideal solution for high side power load switch and can support flexible applications since it is available in various package such as WDFN-6L 2x2, SOT-23-5 and SOT-23-6.
