ADP5061: Charge Complete Behavior

Drostec
on Sep 20, 2019

Hello,

we use ADP5061ACBZ-5-R7.

If device is configured via I²C, charge is complete after configured termination voltage in adress 0x03 is reached. That's the expected behavior.

If device is unconfigured, the device works with Default Termination voltage ( 4,20V ).

After Charge complete ( 0x0B=4C ) the current stops for t(end)= 7,5min.

After this time, a current of ~260µA charges the battery unexpectedly. If I start our controller, current increases to 1,2mA.

I recognized this behavior on 3 pcbs.

Any idea ?

Best regards,

Drostec
