For some applications it may be necessary to measure the load current with very high accuracy. To increase the
device accuracy, different methods can be used, e.g. single point calibration or dual point calibration.
The variance of the sense current at a certain load current depends on the variance of the factor
the variance of the offset current
is described with the parameter Δ
The variance of the sense current offset over the temperature range is defined as shown in

The BTS50060-1TEA provides open load diagnosis in OFF state. This is achieved by monitoring the OUT voltage.
The open load at OFF diagnosis is activated if

application provides high leakage current outside of the BTS50060-1TEA between Vs and OUT, it may be
necessary to use an external resistor
circuitry for enabling / disabling open load detection in OFF state.
