BQ24600: TS setting for 5 to 43 degree C battery charge temperature range

Koshi Ninomiya

Part Number: BQ24600

Hi Team,

My customer wants to set the battery charge temperature range from 5 to 43 degree C.
Their battery pack integrated NTC thermistor, Murata NCP15XH103P03.
What resistor value will R9 and R10 of TS pin be?

Thank you.

Best Regards,

Hi Ninomiya-san,

This thermistor is not compatible with the charger's TS function for those temperatures. Can your customer use a different thermistor with higher Beta (>>3850)?

Regards,

Jeff
