BQ25600D: Correction about BQ25600D charge timer when low temp

TAKASHI SODA

Part Number: BQ25600D

We have a question for charge timer when low temp.

The setting value of the charge timer of BQ25600D is corrected to twice the time when low temperature is detected.
For example, if the charge timer is set to 5 hours when room temperature is detected, the charge timer will be 10 hours when low temperature is detected.

<Question>
Does this correction always occur?
Can this setting be disabled?
If you can disable it, please tell me how to do it.

Thanks.

Hi Takashi Soda,

Yes, during JEITA cool battery temp regulation the charge current is reduced and the safety timer counts at half clock rate.

Yes it can be disabled. Set TMR2X_EN = 0 [REG07 bit 6] to disable the half clock feature.

Best Regards,

Garrett
