说明

The TPS22934 is a small, ultra low ON-resistance (r_ON) load switch with controlled turn on. 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 (V_TH+(typ) = 2.35 V) allowing an easy use of TPS22934 in power-rail sequencing applications.

In TPS22934 a 35- on-chip load resistor is added for output quick discharge when switch is turned off.

In TPS22934, the rise time of the device is internally controlled in order to avoid inrush current. TPS22934 feature a typical rise time of 26 µs with a 3.6-V input.

The TPS22934 is available in an ultra-small space-saving 4-pin CSP package and is characterized for operation over the free-air temperature range of –40ºC to 85ºC.
