8.2.1.2.9 External UVLO
In some cases, an input UVLO level different than that provided internal to the device is needed. This can be accomplished by using the circuit shown in Figure 14. The input voltage at which the device turns on is designated VON and the turnoff voltage is VOFF. First, a value for RENB is chosen in the range of 10 kΩ to 100 kΩ and then Equation 10 is used to calculate RENT and VOFF.

where
- VON = VIN turnon voltage
- VOFF = VIN turnoff voltage
