Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins, e.g. with a 150 resistor in the GND connection and a 15 k resistor in series with the status pin. A resistor for the protection of the input is integrated. RI = internal resistance of the load dump test pulse generator VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839

Add IST, if IST > 0, add IIN, if VIN>5.5 V Requires 150 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 7). External pull up resistor required for open load detection in off state.

ESD zener diodes are not to be used as voltage clamp at DC conditions. Operation in this mode may result in a drift of the zener voltage (increase of up to 1 V).
11) 12)
With additional external pull up resistor An external short of output to Vbb, in the off state, causes an internal current from output to ground. If R GND is used, an offset voltage at the GND and ST pins will occur and the VST low signal may be errorious. 13) Low resistance to V may be detected in the ON-state by the no-load-detection bb
