ADVANCE INFORMATION
Use Equation 41 and Equation 42 to calculate the input UVLO divider resistors, designated as RUV1 and RUV2 in Figure 7-2, given input turn-on and turn-off voltages specified as 6.5V and 4.5V, respectively. Use a 10kΩ resistor in series with the applicable EN pin, designated as RUV3, to increase the effective voltage hysteresis without using higher divider resistances.
Selecting standard 1% resistor values of 105kΩ and 19.1kΩ, calculate the actual input voltage turn-on and turn-off setpoints using Equation 43.
