Absolute Maximum Ratings
Note: Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” the normal operating range. Protection functions
are neither designed for continuous nor repetitive operation.

4) Requires a 150
Ω resistor in GND connection. The reverse load current trough the intrinsic drain-source diode of the power-
MOS has to be limited by the connected load. Power dissipation is higher compared to normal operation due to the votage
drop across the drain-source diode. The temperature protection is not functional during reverse current operation! Input
current has to be limited (see max ratings).
5) No delay time after overtemparature switch off and short circuit in on-state.
6) External pull up resistor required for open load detection in off state.
