Hi Team,

The VCC input range is 12VDC - 24VDC. Charing 1S1P 4.2V 2.5A battery and buck-boost to 12V2A system load concurrently. Once input disconnected, 1S1P battery keep discharging to the 12V2A system load. May we know if this schematic has issues or needs modification?

Hi Christian,

This schemaitc is reference to BQ24610EVM, As we tested on the EVM 12VDC VCC input cannot charge up the 1S1P with 4.2V. Please advise what the problem is?

Thanks,

Steven

Hi Christian,

We find that the 4.2V charing current can only below than 0.2A. Once we set the loading >= 0.2A, the VBAT cannot keep 4.2V and drop to 0.8V. Please check what the problem is, how we can correct set the charging current up to 2.5A?

Thanks,

Steven
