9) 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.

10) Short circuit current limit for max. duration of td(SC) max=450 µs, prior to shutdown

11) 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 7).
