Requires a 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source
diode has to be limited by the connected load. Power dissipation is higher compared to normal operating
conditions due to the voltage drop across the drain-source diode. The temperature protection is not active
during reverse current operation! Input and Status currents have to be limited (see max. ratings page 3 and
circuit page 9).
This range for the current sense ratio refers to all devices. The accuracy of the kILIS can be raised at least by
a factor of two by matching the value of kILIS for every single device.
In the case of current limitation the sense current IIS is zero and the diagnostic feedback potential VST is
High. See figure 2c, page 12.
