Overview
The VND920TR-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, complying with ISO7637 transient compatibility standards. The device includes active current limitation, thermal shutdown, and automatic restart to protect against overload conditions. Additionally, it integrates an analog current sense output that delivers a current proportional to the load current, and it automatically turns off if the ground pin becomes disconnected.
