BQ25619: BQ25619 charge full leakage current

Star Xu

Part Number: BQ25619

The customer test with BQ25619EVM, they tested with a multimeter to measure the leakage current when the battery full charged.

What is the battery leakage current after being fully charged? The datasheet does not have the battery leakage current data after being fully charged.

The leakage current is 60uA, they want to know whether its normal.

Thanks

Hello Star,

The quiescent current ratings are in the data sheet in section 7.6 Electrical Characteristics.

Where are they measuring the current? Is VBUS present and what is the voltage? Do you have anything on system load? What is the state of Q4?

Sincerely,

Wyatt Keller

The system is connected to battery, VBUS 5V, Q4 state is on。The leakage current is 60uA，Is it normal？
