Hi all

Considering that the coin type battery will be charged, we would like to calculate the battery life.

Please give me the maximum value of the current flowing from the PMIC to the coin type battery while the voltage is being supplied to VIN.

According to the table 29 of PF3000.pdf, typical value of coin cell charge current is 60uA and  accuracy is ±30%.

So I think the value of max and min is as follow.

Max: 78uA

Typ: 60uA

Min: 42uA

Are the above coin cell charge current values correct ?

Yes, the maximum charge current to fully discharged coin cell battery of the PF3000 PMIC is in range of 42uA to 78uA.

Have a great day,
Artur
