BQ25600D: Recommended NTC thermistor

Part Number: BQ25600D

Hi,

I know that the recommended NTC thermistor is 103AT-2 that is listed in datasheet. But now the customer would like to use 100kohm NTC with B=4250. Can you recommend to use this NTC thermistor? Please tell me the external divider configuration to meet JEITA profile if you can recommend.

Best Regards,

Satoshi

Hi Hong,

Thank you for your response. They consider NCP15WF104F03RC from Murata and please refer following page for resistance values.

According to your data, RT1 = 36.9 Ohm and RT2 = 140.93k, T1 = 0C, T2 = 13C, T3 = 47C and T5 = 60C.

Hi Hong,

Thank you for calculating RT value and temperature threshold. Do you have spread sheet to calculate these value?

Best Regards,
