9) _{Add IST, if IST > 0}
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) _{If channels are connected in parallel, output clamp is usually accomplished by the channel with the lowest}
V_ON(CL)
12) _{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. 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 8).
