3 Description

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

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.
