3 Description
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.
