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 VCC 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.

2.1Absolute 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.
