The TPS22932B device is a low rON 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
VIN 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.
