7) Integrated protection functions are designed to prevent IC destruction under fault conditions described in the

data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are

not designed for continuous repetitive operation.

8) Requires 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source

diode has to be limited by the connected load. Note that the power dissipation is higher compared to normal

operating conditions due to the voltage drop across the intrinsic 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 2 and circuit page 8).

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 2b, page 10.

10) Valid if Vbb(u rst) was exceeded before.
