10) 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.
11) Device on 50mm*50mm*1.5mm epoxy PCB FR4 with 6cm2 (one layer, 70µm thick) copper area for Vbb
connection. PCB is vertical without blown air.
12) 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 3 and circuit page 7).
13) not subject to production test, specified by design
14) If a ground resistor RGND is used, add the voltage drop across this resistor.
