The under voltage lock out (UVLO) can be adjusted externally using R1 and R2. The EVM is set for a start voltage of 6.528 V and a stop voltage of 6.190 V using R1 = 511 kΩ and R2 = 100 kΩ. Use Equation 3 and Equation 4 to calculate the required resistor values for different start and stop voltages.
