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 BTS5010-1EKB allows limited derating of the
+25 °C). This derating is described by the parameter Δ
assuming one calibration point at nominal load at +25 °C.
The blue line indicates the ideal
The red lines indicate the derating on the parameter across temperature and voltage, assuming one calibration
point at nominal temperature and nominal battery voltage.
The grey lines indicate the
