Charger designed with BQ24780S
issue is when battery is disconnected from charger and the load is drived directly from Vsys for 2A say, charger is getting off at lower voltage range, say my input is 12V and Bat is 8.4V , and when battery disconnected, it loads and resets till voltage increased to13V. but when Battery is connected, it works fine without loading at 12V itself.
may i know any UVLO settings done,. .ACDET is designed to power on at 8.5V so ,it is not an issue
