TPS22924CYZPR General 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.
