TPS2291xx Ultra-small, Low On Resistance Load Switch With Controlled Turn-on

3 Description
The TPS22910A, TPS22912C, and TPS22913B/C
are small, low r
ON
load switches with controlled turn
on. The device contains a P-channel MOSFET that
can operate over an input voltage range of 1.4 V to
5.5 V. The switch is controlled by an on/off input
(ON), which is capable of interfacing directly with low-
voltage GPIO control signals.
The TPS22910A, TPS22912C, and TPS22913B/C
devices provide reverse current protection in ON and
OFF states. An internal reverse voltage comparator
disables the power-switch when the output voltage
(V
OUT
) is driven higher than the input voltage (V
IN
), by
V
RCP
, to quickly (10 µs typ) stop the flow of current
towards the input side of the switch. Reverse current
protection is always active, even when the power-
switch is disabled. Additionally, under-voltage lockout
(UVLO) protection turns the switch off if the input
voltage is too low.
The TPS22913B/C contains a 150-Ω on-chip load
resistor for quick output discharge when the switch is
turned off.
This family of devices have various slew rate options
to avoid inrush current (see
Device Comparison
Table
for details), are available in an ultra-small,
space-saving 4-pin WCSP packages, and are
characterized for operation over the free-air
temperature range of –40°C to 85°C.
