I follow the reference schematic as below picture to design my circuit, but i find a problem.
When I want to charge my coin battery(PMIC Vin in is on and coin battery is plug in) and waiting a period of time.
I plug out the coin battery then measurement the voltage of coin battery.
I find the voltage is 2.6 V like the beginning, i confirm the LICELL pin is correct output the 3.0 V charge voltage.
Can someone help me? thank you.
