Description
The VND810P-E is a monolithic device designed in STMicroelectronics™ VIPower™ M0-3 technology, intended for driving any kind of load with one side connected to ground.
Active V against low energy spikes (see ISO7637 transient compatibility table).
Active current limitation combined with thermal shutdown and automatic restart protect the device against overload.
The device detects open-load condition both in on-state and off-state. Output shorted to V detected in the off-state. Device automatically turns off in case of ground pin disconnection.

2 Electrical specifications

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.
