TPS22924C,pdf(Ultra-Low ON-Res

The TPS22924C is a small, ultra-low r_ON load switch with controlled turn on. The devices contain N-channel MOSFETs 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- on-chip load resistor is added for output quick discharge when switch is turned off. The rise time of the device is internally controlled to avoid inrush current. The TPS22924C features a rise time of 800 µs at 3.6 V.

The TPS22924C 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.
