Question
How to use EN threshold to set the input voltage UVLO?
Answer
The ADP2386 has a precision enable input with a typical rising threshold of
1.17V, which can be used to program the UVLO threshold of the input voltage. A
resistor divider from PVIN through EN to GND can set both the rising and
falling thresholds of the input voltage UVLO.
For detailed information, please refer to ADP2386 data sheet, page17,
PROGRAMMING THE INPUT VOLTAGE UVLO section.
