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.
If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest

Requires a 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source
diode has to be limited by the connected load. Power dissipation is higher compared to normal operating
conditions due to the voltage drop across the 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 8).
17) If ground resistors R
GND are used, add the voltage drop across these resistors.
