7.2.1 Implementing Adjustable Hysteresis

A comparator can produce “chatter” (multiple transitions) at the output when there are noise or signal variations around the reference threshold; this causes the output to change states in rapid random successions as the comparator input goes above and below the threshold of the reference. This usually occurs when the input signal is moving very slowly across the switching threshold of the comparator. This problem can be prevented by using the internal hysteresis feature of the TLV3603-EP.

The TLV3603-EP has a LE/HYS pin that allows for variable internal hysteresis depending on the resistor value connected between the pin and VEE, where increasing the resistance decreases the hysteresis to a minimum level.
