3.3.1.3.2 DEF_PTC_TAU_TARGET
The calibration target applies a limit to the charge transfer loss allowed, where a higher setting of a target ensures a greater proportion of full charge is transferred. The PTC_TAU_TARGET is applicable only when CAL_AUTO_TUNE_NONE is NOT used. The time taken for a sensor to charge varies depending upon the values used here.
Bits 7:4 Calibration target
| Values | Description |
|---|---|
| CAL_CHRG_2TAU | This gives 2 times the RC time constant for charging the sensor |
| CAL_CHRG_3TAU | This gives 3 times the RC time constant for charging the sensor |
| CAL_CHRG_4TAU | This gives 4 times the RC time constant for charging the sensor |
| CAL_CHRG_5TAU | This gives 5 times the RC time constant for charging the sensor |
