Description
The VN920DB5-E is a monolithic device designed using STMicroelectronics™ VIPower™ M0-3 technology. The VN920DB5-E is intended for driving any type of load with one side connected to ground. The active V protects the 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-state and off-state. In the off-state the device detects if the output is shorted to V turns-off in the case where the ground pin becomes disconnected.

Stressing the device above the rating listed in the Ta bl e 3 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.
