Description

The VND810SP is a monolithic device designed
using| STMicroelectronics™ VIPower™ M0-3
Technology. The VND810SP is intended for
driving any type of multiple load with one side
connected to ground.

The Active V
device against low energy spikes (see ISO7637
transient compatibility table). Active current
limitation combined with thermal shutdown and
automatic restart protects the device against
overload.

The device detects the open-load condition in
both the on-state and off-state. In the off-state the
device detects if the output is shorted to V
device automatically turns off in the case where
the ground pin becomes disconnected.

2.1 Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality document.
