Part Number: BQ24600

It is not full charged and an error occurs as follows.

*The Vbat set voltage is 13.1122 V (430k/82k resistance) and The maximum voltage of battery is 13.2V.

Please let me know if this problem is the wrong charging voltage and current setting or if there is any other reason.

2ch_STAT, 3ch_PG, 4ch_Batt. Charging Current

For your information, the normal waveform is as follows.

Thanks

Hi David,

Can you clarify what is the error you are seeing? Is it the battery not fully charged or other error?

The charge current waveform looks like a normal charging profile.

Where is the Ch1 (yellow) waveform measured?

Is the measured on a custom board? If so, can you provide the schematic?

Regards.

Can you tell me your email address to send the schematic.

Thanks

Hi David,

I have sent you an friend request on e2e. You can send me the schematic with direct message.

Can you specify what is the Ch1 (yellow) waveform measurement?

Regards.

Hi Tommy

The schematic was delivered in a direct message.
I have another inquiry.

The charging current was set to 2.285a.
If the termination current is 1/10, it is 0.2285a, right?

However, in reality, the termination current is less than or equal to 100 mA.
What's the problem?

Thanks
