3 Description
The TPS22924x is a small, low R_ON 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 TPS22924B features a rise time
of 100 µs at V_IN = 3.6 V while the TPS22924C has a
rise time of 800 µs at V_IN = 3.6 V.
The TPS22924x is available in an ultra-small space-
saving 6-pin CSP package and is characterized for
operation over the free-air temperature range of
–40ºC to 85ºC.
