Rev 1.0 DIO7300 5.5V rated 2A capable slew rate controlled load switch Features Descriptions 1.8V to 5.5V operation voltage range The DIO7300 is a Low On-Resistance Nchannel Low quiescent current < 1A when disabled MOSFET controlled by a softstart sequence of Reverse current blocking when switch is off 2.5ms for mobile applications. 60m NMOSFET DC Current Up to 2A The low RDS(on) allows system supplying or Peak Current Up to 5A battery charging up to DC 2A.The device is enable Builtin SoftStart 2.5ms automatically if a power supply is connected on Active High with Integrated Bridge V pin (active High) and maintained off if no power IN PbFree Device SOT23-5 input(internal pull down). Due to the current consumption optimization, the Applications leakage current is drastically decreased from the Cell Phone and Digital Camera battery connected to the device, which allows PDA and Notebook extending the battery life.
