DESCRIPTION

The VND830LSP is a monolith ic device made by using STMicroelectronics VIPower M0-3 Technology, i ntended for dr iving any ki nd of load with one side connected to ground. Active VCC pin voltage clamp protec ts the device against low energy spikes (see ISO7637 transient

compatibility table). Active current limitation combined with thermal shutdown a nd automatic restart protects the device against over load. 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. Device automatically turns off in case of ground pin disconnection.
