Dear team,

For the EN pin, can we connect an external resistor ladder to EN to GND to achieve UVLO function?

Thanks & Best Regards,

Hi Sherry,

The EN pin high and low thresholds are not accurate enough to be used as UVLO. As you can see below, the low threshold varies from 0.5V to 1.2V.

So, the EN pin is not recommended to be used for UVLO functionality.
