Original question:

BQ24092 charge current setting question

BQ24092: Maximum termination current setting

user4292685
Intellectual 935 points
Part Number: BQ24092

I would like to program the termination current setting as 100% of Iout, not 50% of Iout as datasheet.

Is it possible to program it?

And if I set Rpre-tem resistor as 18kohm, what does it happen?

Regards,

    Hi,

    We do not recommend this as the device turns off based on the current if the charge current reaches the termination current. If the desire is to disable termination, you can pull the TS pin high. This will also disable TS monitoring and timers.

    Thank you for your quick reply.

    Actually I do not wan to stop the timer, so TS pin high does not solve this issue.

    Could you tell me what happen if I set Rpre-term resistor as 18kohm?

    Regards,

    Hi,

    This is not recommended as previously mentioned. The device will not accurately terminate I believe. If the device detects that the current is at 100% fast charge current (which is the programmed termination current), the device will end charging. 

    Is there a reason to set the termination current to 100% of fast charge?

    Best Regards,
