7.3.2.2 SENSE Hysteresis

TPS3710x-Q1 device offers built-in hysteresis around the UV and OV thresholds to avoid erroneous OUT A and

OUT B deassertions. The hysteresis is opposite to the threshold voltage; for overvoltage options the hysteresis

is subtracted from the positive threshold (VITP), for undervoltage options hysteresis is added to the negative

threshold (VITN). Figure 7-4 and Figure 7-5 highlight the OUT A and OUT B behavior based on a window variant

with standard OUT A/B.
