open-in-new Find other Load switches


The TPS22901, TPS22902, and TPS22902B are small, low ON-resistance (rON) load switches with a controlled turnon. These 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 can interface directly with low-voltage control signals. In the TPS22902 and TPS22902B, an 88-Ω on-chip load resistor is added for output quick discharge when the switch is turned off.

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