Description

TPS22901, TPS22902, and TPS22902B are ultra-small, low ON resistance (rON) load switches with controlled turn on. The devices contain a P-channel MOSFET that operates over an input voltage range of 1.0 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 TPS22902 and in TPS22902B, a 120- on-chip load resistor is added for output quick discharge when the switch is turned off.

TPS22901, TPS22902, and TPS22902B are available in a space-saving 4-terminal WCSP with 0.4-mm pitch (YFP). The devices are characterized for operation over the free-air temperature range of –40°C to 85°C.
