9.1.2 External Hysteresis
The TLV3201-Q1 and TLV3202-Q1 have a hysteresis transfer curve (shown in Figure 27) that is a function of three components: VTH, VOS, and VHYST.
- VTH: the actual set voltage or threshold trip voltage
- VOS: 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: internal hysteresis (or trip window) that is designed to reduce comparator sensitivity to noise.
