3.6V, 1A, 46mΩ Load Switch


This product is not recommended for new designs.

Replaced By TPS22912C – The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


The TPS22907 is a small, low RON load switch with controlled turnon. The device contains a P-channel MOSFET that operates over an input voltage range of 1.1 V to 3.6 V. The switch is controlled by an on and off input (ON), which can interface directly with low-voltage control signals.

The TPS22907 is available in a space-saving 4-terminal WCSP with 0.5-mm pitch (YZT). The device is characterized for operation over the free-air temperature range of –40°C to 85°C.
