Overview
The VNQ810M-E, produced by STMicroelectronics, is a quad-channel high-side driver (HSD) designed for driving multiple loads with one side connected to ground. This device is formed by assembling two VND810 chips in a single SO-28 package, utilizing STMicroelectronics' VIPower M0-3 technology. It is intended for applications requiring robust and reliable high-side switching, with features such as active VCC pin voltage clamp, current limitation, thermal shutdown, and automatic restart. The VNQ810M-E offers comprehensive protection mechanisms including undervoltage and overvoltage shutdown, loss of ground protection, and shorted load protection.
