7.3.4 Overvoltage (OV) and Undervoltage Protection (UVLO)
TPS12000-Q1 has an accurate undervoltage protection (< ±2%) using EN/UVLO pin and an accurate overvoltage protection (< ±2 %), providing robust load protection. Connect a resistor ladder as shown in Figure 7-11 for undervoltage and overvoltage protection threshold programming.
