Product Details

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.
