Overview
The VN02H, produced by STMicroelectronics, is a high-side smart power solid-state relay designed using the VIPower technology. This monolithic device is intended for driving resistive or inductive loads with one side grounded. It features a 5V logic level compatible input and includes built-in thermal shut-down, under-voltage shut-down, and an open drain diagnostic output. The VN02H is packaged in a Pentawatt-5 configuration, available in vertical, horizontal, and in-line lead configurations.
