8.4.2 Internal Hysteresis
The device hysteresis transfer curve is shown in Figure 37. This curve is a function of three components: VTH, VOS, and VHYST:
- VTH is the actual set voltage or threshold trip voltage.
- VOS is the internal offset voltage between VIN+ and VIN–. This voltage is added to VTH to form the actual trip point at which the comparator must respond to change output states.
- VHYST is the internal hysteresis (or trip window) that is designed to reduce comparator sensitivity to noise
(4.2 mV for the TLV7011).
