The device contains an N-channel MOSFET that can operate over an input voltage range of 0.65 V to 3.6 V and pulsed switch currents up to 4 A. An integrated charge pump biases the NMOS switch in order to achieve a minimum switch ON resistance (RON). The switch is controlled by an on and off input (ON), which is capable of interfacing directly with lowvoltage control signals. The TPS22970 is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off...
