Evaluates: MAX20084/ MAX20084 Evaluation Kit/ MAX20084B MAX20084 Evaluation System General Description Quick Start The MAX20084 evaluation kit (EV kit) is a fully assembled Required Equipment and tested surface-mount PCB used to evaluate the MAX20084 EV kit MAX20084/MAX20084B automotive dual-antenna power 2 12V, 1A power supply supply with I C interface. Each channel can be indepen- dently configured to operate either as a switch or as an Voltmeter 2 LDO with regulated adjustable output voltage using I C. MINIQUSB+ interface board with USB cable The EV kit demonstrates the devices features: adjustable User-supplied Windows-compatible PC with spare current limit, adjustable overcurrent detection, adjust- USB port able open-load detection, and adjustable warning-current detection. The output current of each channel can be Note: In the following sections, software-related items are 2 monitored using I C or by measuring an analog output identified by bolding.
