Overview
The VN808-E is a monolithic device from STMicroelectronics, realized in the VIPower M0-3 technology. It is designed as an octal channel high-side driver, intended to drive any kind of load with one side connected to ground. This device is particularly suited for industrial applications and complies with IEC 61131 standards. It features active current limitation, thermal shutdown, and automatic restart to protect against overload conditions. The device also includes protections such as junction overtemperature protection, case overtemperature protection, short-circuit load protection, and undervoltage shutdown. Additionally, it has a very low standby current and compliance with IEC 61000-4-4 tests up to 4 kV.
