The MAX25222 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate MAX25222 automotive 4-channel TFT-LCD power supply with VCOM Buffer. Each output rail (AVDD, NAVDD, VGON, VGOFF, and VCOM) can be independently adjusted through I2C. The EV kit demonstrates the device’s features: adjustable output voltage, fault protection, VCOM temperature compensation, nonvolatile memory programming, and extensive diagnostics to aid in fulfilling ASIL-B safety level.
The EV kit exposes an I2C interface which can operate in conjunction with the MINIQUSB+ adapter or a third party I2C master like a general-purpose microcontroller. The EV kit also includes Windows®-compatible software that provides a simple graphical user interface (GUI) for exer- cising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
