DESCRIPTION

The VNQ830M is a quad HSD formed by assembling two VND830M chips in the same SO-28 package. The VND830M is a monolithic device made by using| STMicroelectronics VIPower M0-3 Technology. The VNQ830M is intended for driving any type of multiple loads with one side connected to ground.

Active VCC pin voltage clamp 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 open load condition both in on and off state. The openload threshold is aimed at detecting the 5W/12V standard bulb as an openload fault in the on state. Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection.
