3 Description
The TPS22930 is a small, low RON load switch 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 control signals. The
TPS22930 is active high enable.
The TPS22930 device provides circuit breaker
functionality by disabling the body diode during
reverse voltage (also known as reverse current)
situations. Reverse current protection is active only
when the power-switch is disabled (off). The device
disengages the body diode when the output voltage
(VOUT) is driven higher than the input (VIN) to stop the
flow of current towards the input side of the switch.
Additionally, under-voltage lockout (UVLO) protection
turns the switch off if the input voltage is too low.
The slew rate of the device is internally controlled in
order to avoid inrush current.
The TPS22930 is available in an ultra-small, space-
saving 4-pin CSP package and is characterized for
operation over the free-air temperature range of
–40°C to 85°C.
