Overview
The VND920-E is a double-channel high-side solid-state relay 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, as well as active current limitation, thermal shutdown, and automatic restart to safeguard against overload conditions. The device also includes an analog current sense output that provides a current proportional to the load current and automatically turns off if the ground pin becomes disconnected.
