TPS22921,TPS22922,TPS22922B,pd

TPS22921, TPS22922, and TPS22922B are ultra-low r_ON load switches with controlled turn on. TPS22921/2/2B contain an ultra-low r_ON P-channel MOSFET that can operate over an input voltage range of 0.9 V to 3.6 V. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. In TPS22922 and in TPS22922B, a 120- on-chip load resistor is added for output quick discharge when switch is turned off. The rise time (slew rate) of the device is internally controlled in order to avoid inrush current: TPS22921 and TPS22922 feature a 30 µs rise time whereas TPS22922B is 200 µs.

TPS22921, TPS22922, and TPS22922B feature ultra low quiescent and shutdown current and are available in space-saving 6-terminals wafer-chip-scale packages (WCSP: YZP with 0.
