Can't charge coin battery through PFUZE3000 PMIC LICELL pin

Question asked by LEE YU LIN on May 25, 2017

HI,

 

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.

 

Best regard,
