7.4.2 Internal Hysteresis

The device hysteresis transfer curve is shown in Figure 7-1. 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
    (7 mV for both TLV703x and TLV704x).
