Overview
The VNQ830 is a quad-channel high-side driver (HSD) produced by STMicroelectronics. It is formed by assembling two VND830 chips in a single SO-28 package. This device is manufactured using STMicroelectronics' VIPower M0-3 Technology and is designed to drive multiple loads with one side connected to ground. The VNQ830 features a robust set of protection mechanisms, including active VCC pin voltage clamp, current limitation, thermal shutdown with automatic restart, and detection of open-load conditions in both on and off states. It also includes protections against shorted loads, undervoltage and overvoltage, loss of ground, and reverse battery conditions.
