TPS22934 SLVSAD4A – AUGUST 2010 – REVISED JUNE 2013 www.ti.com APPLICATION INFORMATION ON/OFF Control The ON pin controls the state of the switch. The TPS22934 has built-in hysteresis on its control inputs. The load switch is active when the ON voltage is greater than the positive going voltage threshold (VTH+). If the ON voltage is lower than the negative going voltage threshold (VTH-), then the pass FET is deactivated and the active pulldown from VOUT to GND is activated.
