Description
The VNQ810 is a quad HSD formed by
assembling two VND810 chips in the same SO-28
package. The VND810 is a monolithic device
made using| STMicroelectronics VIPower M0-3
Technology. The VNQ830 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 and off state.
In the off state the device detects if the output is
shorted to V
in the case where the ground pin becomes
disconnected.
pin voltage clamp protects the
CC
. The device automatically turns off

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.

Note: To ensure long term reliability under heavy overload or short circuit conditions, protection
and related diagnostic signals must be used together with a proper software strategy. If the
device is subjected to abnormal conditions, this software must limit the duration and number
of activation cycles.
