TPS22960 www.ti.com SLVS914B – APRIL 2009 – REVISED AUGUST 2013 APPLICATION INFORMATION ON/OFF Control The ON pin controls the state of the switch. Activating ON continuously holds the switch in the on state so long as there is no fault. ON is active HI 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.
