Protection and diagnostic

OL (overload) pin

The integrated open drain transistor is active (turn-on) in case of overload conditions.

Overload is detected when the output current exceeds the IOLS-PEAK or IOHS-PEAK threshold.

The open drain transistor is active with a small delay (tOL), after the overload condition is

detected. Overload is not detected when EN/DIAG pin is at a low logic level. Overload is

not detected in cut-off conditions: if the output stage remains in a current limitation (OL)

condition for a time longer than the tdOUT delay, the output stage is turned off (cut-off

condition) and the OL pin is released. The output stage is restarted after the trOUT restart

time.

Reverse polarity protection

The integrated reverse polarity protection (RPP) avoids any damage in the IC in case of

wrong connection of its pins to the supply rail lines. These protected pins, despite reverse

polarity, are: VCC, GND, OUTH, OUTL and I/Q.
