TPS22913 SLVSB20 – SEPTEMBER 2011 www.ti.com 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 1.8-V, 2.5-V or 3.3-V GPIOs.
