BQ24640: Leakage current from TS-pin

Kurumi Hasegawa

Part Number: BQ24640

Hi team,

Could you share the leakage current from TS-pin?

The background of this question is that when TS-pin function is not needed, same value of RT1 and RT2 required.

The appropriate range for RT1 and RT2 would be to set the current =1000*leakage (correct?), so I’d like to know leakage current.

Dear Kurumi,

For a 103AT NTC thermistor, we recommend using 430 kOhm for RT2 and 9.31 kOhm for RT1. If no thermistor is being used, you can swap out the 430 kOhm for a 10 kOhm at RT2.

Thanks,

Mike Emanuel
