RT9722 145mΩ, 1.5A Power Switch with Programmable Current Limit General Description 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.
