TPS22932B is a low rON load switch with controlled turn on. It contains an ultra-low rON
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 non-inverter. All inputs can be connected to VIN or GND. The control pins can be connected to low voltage GPIOs allowing it to be controlled by whatever 1.2-V, 1.8-V, 2.5-V, or 3.3-V logic signals while keeping extremely low quiescent current.
A 120-
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.
