Analog Devices / Maxim Integrated MAX25222 Evaluation System (MAX25222EVSYS)

Analog Devices MAX25222 Evaluation System (MAX25222EVSYS) is a demonstration and development platform for the MAX25222 Automotive 4-Channel TFT-LCD Power IC. Each output rail (AVDD, NAVDD, VGON, VGOFF, and VCOM) can be independently adjusted through the I2C interface. The Evaluation System demonstrates the device’s features, such as adjustable output voltage, fault protection, VCOM temperature compensation, nonvolatile memory programming, and extensive diagnostics to aid in fulfilling ASIL-B safety levels.

The Analog Devices MAX25222 Evaluation System includes the MAX25222 Evaluation Board, which connects to a PC using the included MINIQUSB+ Interface Board. The MAX25222EVSYS software provides a simple Graphical User Interface (GUI) for demonstrating the features of the IC.
