The devices contain a P-channel MOSFETs that can operate over an input voltage range of 1.5 V to 3.6 V. The switch is controlled by an ON/OFF input (ON), which has built-in hysteresis (VTH+(typ) = 2.35 V) allowing an easy use of TPS22934 in power-rail sequencing applications. In the TPS22934 a 35-Ω on-chip load resistor is added for output quick discharge when ...
