8.3.6 Overvoltage (OV) and Undervoltage Protection (UVLO)
TPS4811x-Q1 has an accurate undervoltage protection (< ±2 %) using EN/UVLO pin.
TPS48110-Q1 has an accurate overvoltage protection (< ±2 %), providing robust load protection. Connect a resistor ladder as shown in Figure 8-12 for undervoltage and overvoltage protection threshold programming.
