TPS22924C Load Switch with Low ON Resistance

Texas Instruments' ultra-small, ultra-low rON load switch with controlled turn on

TPS22924C Load Switch with Low ON ResistanceTexas Instruments' TPS22924C is a small, ultra-low rON load switch with controlled turn on. The devices contain N-channel MOSFETs that can operate over an input voltage range of 0.75V to 3.6V. 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 1250Ω 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 TPS22924C features a rise time of 800µs at 3.6V.
