See also VON(CL) in table of protection functions and circuit diagram on page 8. Measured with load; for the whole device; all channels off Add IST, if IST > 0 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 VON(CL)

Requires a 150 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. 18) not subject to production test, specified by design

Parallel switching of channel 1 and 2 is easily possible by connecting the inputs and outputs in parallel (see truth table). If switching channel 1 to 2 in parallel, the status outputs ST1 and ST2 have to be configured as a 'Wired OR' function with a single pull-up resistor.
