Overview
The VNI8200XP, produced by STMicroelectronics, is a monolithic 8-channel driver designed using the VIPower™ technology. This IC is intended to drive any type of load with one side connected to ground, operating within a voltage range of 10.5 V to 36 V. It features a very low supply current, a selectable SPI or parallel control interface, and a high-efficiency 100 mA micropower step-down switching regulator. The device includes a 4x2 LED matrix for efficient output status indication and provides comprehensive protection mechanisms such as per-channel current limitation, thermal shutdown, and overvoltage protection.
