The MAX20084 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate MAX20084/MAX20084B automotive dual-antenna power supply with I2C interface. Each channel can be independently configured to operate either as a switch or as an LDO with regulated adjustable output voltage using I2C. The EV kit demonstrates the device’s features: adjustable current limit, adjustable overcurrent detection, adjustable open-load detection, and adjustable warning-current detection. The output current of each channel can be monitored using I2C or by measuring an analog output voltage. The EV kit exposes an I2C interface that can operate in conjunction with either the MINIQUSB+ adapter or a third-party I2C master, such as a general-purpose microcontroller. The EV kit also includes Windows-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
