ABSTRACT:
An apparatus for providing programmable hysteresis control using an enable pin of a device is disclosed. An enable pin is configured to receive an input signal to enable and disable an associated device responsive to the input signal. A current sink is attached to the enable pin and is responsive to circuitry that disables the current sink responsive to application of the input signal at a first voltage level and enables the current sink responsive to application of the input signal at a second voltage level.
