Overview
The VN820(011Y) is a high-side driver designed by STMicroelectronics using their 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 to protect against low energy spikes and includes active current limitation, thermal shutdown, and automatic restart to safeguard against overloads. The device also detects open-load conditions in both on-state and off-state modes and can automatically turn off if the ground pin becomes disconnected.
