TPS22920 www.ti.com SLVSAY8A – JUNE 2011 – REVISED JULY 2013 APPLICATION INFORMATION ON/OFF CONTROL The ON pin controls the state of the switch. Asserting ON high enables the switch. ON is active high and has a low threshold, making it capable of interfacing with low-voltage signals. The ON pin is compatible with standard GPIO logic threshold. It can be used with any microcontroller with 1.2-V, 1.8-V, 2.5-V or 3.3-V GPIOs.
