The VNQ860 and VNQ860SP are monolithic devices made using STMicroelectronics VIPower M0-3 Technology, intended for driving any kind load with one side connected to ground. Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. Device automatically turns off in case of ground pin disconnection. This device is especially suitable for industrial applications in norms conformity with IEC1131 (Programmable Controllers International Standard).
The VNQ860 and VNQ860SP are monolithic quad‑channel high‑side drivers built with STMicroelectronics VIPower MOS technology. They are intended for driving loads with one side tied to ground and include active current limitation, thermal shutdown, and automatic restart to protect against overload and loss of ground.
The manual details absolute maximum ratings, electrical and thermal characteristics, pin‑out diagrams, mechanical dimensions for both SO‑20 and PowerSO‑10 packages, and recommended PCB layout and pad recommendations. Safety notices and warranty statements are included at the end of the document.
