In some applications a better accuracy is required around half the nominal current
requirement, a calibration on the application is possible. To avoid multiple calibration points at different load and
temperature conditions, the BTS5020-2EKA allows limited derating of the
T
current, assuming one calibration point at nominal load current and +25 °C.

The green lines indicate the derating on the parameter across temperature and voltage, assuming one calibration
point at nominal temperature, nominal battery voltage and nominal load current.
