BQ21061: Need TS pin calculation tool to design JEITA profile with different NTC

Part Number: BQ21061

Hi team,

My customer design BQ21061 but since this project used NTC that is 68K ohm/Beta 4700K, it has a different definition form the BQ21061 charger.

If they want to meet the JEITA profile , they should modify TS_HOT, TS_WARM, TS_COOL and TS_COLD registers.

Could you provide calculation tool for customer and guide them  how to calculate VTS threshold of NTC 68K ohm, thank you.
