BQ34110: How the error on the Thermistor translate in temperature

Cédric St-Amand

Part Number: BQ34110

Hi,

We are looking for the temperature error depending on the thermistor tolerance. In example, if we have a thermistor value that is X ohm above the theoretical value, how the temperature is affected.

We recommend thermistors based on the internal calculation of coefficients that are set by hw. Therefore we urge you not to use thermistors that are incompatible with the Semitec 105AT type. This can cause nonlinearities in performance.

But still, do you have some data so we can evaluate it temperature drift vs thermistor value. We are procuring a battery pack and we may be forced to used not to use the perfect fit and evaluated what the impact is.

We do have char data but I don't think we provide the curves to the customer.
