The TPS22932B device is a low r_ON load switch with controlled turnon. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.1 V to 3.6 V.

The switch is controlled by eight patterns of 3-bit input. The user can choose the logic functions MUX, AND, OR, NAND, NOR, inverter, and noninverter. All inputs can be connected to V_IN or GND. The control pins can be connected to low-voltage GPIOs allowing the switch to be controlled by either 1.2-V, 1.8-V, 2.5-V, or 3.3-V logic signals while keeping extremely low quiescent current.

A 120-Ω on-chip load resistor is available for output quick discharge when the switch is turned off. The rise time (slew rate) of the device is internally controlled to avoid inrush current: the rise time of TPS22932B is 165 µs.

TPS22932B is available in a space-saving 6-pin DSBGA (YFP with 0.4-mm pitch). The device is characterized for operation over the free-air temperature range of –40°C to 85°C.
