Overview
The VN820-B5 is a high-side driver IC produced by STMicroelectronics, designed using the VIPower® M0-3 technology. This monolithic device is intended for driving various types of loads with one side connected to ground. It features an active VCC pin voltage clamp that protects the device against low energy spikes. The VN820-B5 combines active current limitation with thermal shutdown and automatic restart, ensuring robust protection against overload conditions. It also includes detection for open-load conditions in both on-state and off-state modes, as well as protection against output shorted to VCC and ground pin disconnection.
