Part Number: BQ25601

Dear Sir,

How much does the charge current decrease during thermal regulation?

Hi Chiaki,

In thermal regulation, ICHG can taper all the way down to zero depending on how high the IC temperature is. Please see Figure 9 below for more details on how ICHG changes during thermal regulation.

Best regards,

Angelo

Hi Angelo,

Thank you for your reply.

Sorry, I missed to see Fig9.
What is difference between Fig9 and Fig8?

Best regards,

Hi Chiaki,

I believe Figure 8 is mislabeled and actually shows the system current vs. junction temperature, not the charge current vs. junction temperature. To understand how thermal regulation affects ICHG, please refer to Figure 9 instead.

Best regards,

Angelo
