Hi team.

I'd like to know about temperature protection for TSpin.

My customer do not use OTG mode.

I think the datasheet only describes in OTG mode.

Is the temperature protection equivalent to OTG mode when OTG mode is disabled?

Could you tell me about detail for temperature protection without OTG mode?

Sincerely.

Kengo.

Dear Kengo,

Please refer to Section 8.3.7.4.1. The temperature protection for charging mode (boost) is fully explained there.

Thanks,

Hi Mike.

My customer want to don't stop charging at low temperature(~0C).

Is there a way to control it?

Sincerely.
Kengo.

Kengo,

Please read Section 8.3.7.4.1 in full as it demonstrates the solution to this problem as well. You can adjust the voltage on TS such that T2 corresponds to 0C and extend the charge current temperature range with a register setting, or alternatively make T1 correspond to 0C.

Thanks,

Mike Emanuel
