1Integrated 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 .

2not subject to production test, specified by design

3 see also VON(CL) in circuit diagram on page 7

4Requires 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 current has to be limited (see max. ratings page 3).
