DESCRIPTION
The VNQ810M is a quad HSD formed by assembling two VND810M chips in the same SO-28 package. The VND810M is a monolithic device made by using STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load 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 current limitation threshold is aimed at detecting the 21W/12V standard bulb as an overload fault. The device detects open load condition both in on and off state . Output shorted to VCC is detected in the off state. Device automatically turns off in case of ground pin disconnection.
