8.3.2 OVP Threshold

TPD2S703-Q1 tpd2S-ovp-diagram.gifFigure 22. OVP Threshold

The OVP Threshold VOVP is set by VREF according to Equation 1, Equation 2 and Equation 3.

Equation 1. TPD2S703-Q1 OVP_Th_Equation_1.gif
Equation 2. TPD2S703-Q1 OVP_Th_Equation_2.gif
Equation 3. TPD2S703-Q1 OVP_Th_Equation_3.gif

Equation 1, Equation 2 and Equation 3 yield the typical VOVP values. See the parametric tables for the minimum and maximum values that include variation over temperature and process. Figure 22 gives a graphical representation of the relationship between VOVP and VREF.

VREF can be set either by an external regulator (Mode 0) or an internal adjustable regulator (Mode 1). See the VREF Operation section for more details on how to operate VREF in Mode 0 and Mode 1.
