3 Description
The TPS22924D is a small, low RON load switch with controlled turn on. The device contains a N-channel
MOSFET that can operate over an input voltage
range of 0.75 V to 3.6 V. An integrated charge pump
biases the NMOS switch to achieve a minimum
switch ON resistance. The switch is controlled by an on/off input (ON), which is capable of interfacing
directly with low-voltage control signals.
A 1250 Ω on-chip load resistor is added for output
quick discharge when the switch is turned off. The
rise time of the device is internally controlled to avoid
inrush current. The TPS22924D features a rise time
of 6200 μs at 3.6 V.
The TPS22924D is available in an ultra-small, spacesaving
6-pin CSP package and is characterized for
operation over the free-air temperature range of
–40ºC to 85ºC.
