Other Parts Discussed in Thread: BQ25895, BQ27520-G4

Hello,

I have use in BQ25895 battery Charger IC and bq27520-g4 fuel gauge in our application and I don't need to use TS pin or negative temperature coefficient thermistor.

Please let me know what I have to do TS pin in BQ25895 and bq27520-g4.

Thanks.

For bq25895, the TS pin needs a resistor divider from REGN to set the same voltage as if the thermistor were present as shown in figure 47 (for example, a 5.23kohm top resistor and 10kohm||30.1kohm bottom resistor).

Hi jeff,

Thanks for prompt reply.

That means we need to set cold level thermistor Sense threshold level of Temp detection using resistor divider network.

Thanks.

No, that should set it between JEITA WARM and JEITA COOL.
