Overview
The VNQ810 is a quad high-side driver (HSD) produced by STMicroelectronics. It is formed by assembling two VND810 chips in a single SO-28 package. This device is designed using STMicroelectronics' VIPower M0-3 technology and is intended for driving multiple loads with one side connected to ground. The VNQ810 features advanced protection mechanisms, including undervoltage and overvoltage shutdown, loss of ground protection, and shorted load protection. It also includes active current limitation, thermal shutdown, and automatic restart to protect against overload conditions.
