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 CC pin voltage clamp protects the 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.

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.
