Description
The VND830AEP-E is a monolithic device made
using| STMicroelectronics VIPower™ M0-3
Technology. The VND830AEP-E 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).
This device has two channels in high side
configuration; each channel has an analog sense
output on which the sensing current is
proportional (according to a known ratio) to the
corresponding load current. Built-in thermal
shutdown and outputs current limitation protect
the chip from over temperature and short circuit.
The 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.
