Power Switch 1A 4-Pin DSBGA T/R

The TPS22934 is a small, low ON-resistance (rON) load switch with controlled turnon. 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-O on-chip load resistor is added for output quick discharge when switch is turned off. In the TPS22934, the rise time of the device is internally controlled to avoid inrush current. The TPS22934 features a typical rise time of 26 µs with a 3.6-V input. The 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 –40°C to 85°C.
