Evaluation Kits

MAX20484EVKIT

Evaluation Kit for the MAX20484 Voltage Monitor with Watchdog and Clock Monitor

Buy Now View Details

Features and Benefits

  • Easy to Reach Test Points for Debugging
    • Pre and Post Filter Connections
    • Input Jumpers for Logic Probe Connections
  • I2C Communication Header Allows for Flexible Interfacing
  • Maxim PICO2MINIQ# Communication Board
  • Used with the MAX20484 Graphical User Interface
  • Fully Assembled and Tested

Product Details

The MAX20484 evaluation kit (EV kit) provides a platform to evaluate the performance and features of the MAX20484 Power System Monitor. The voltage monitoring accuracy, watchdog, power sequence recorder, and clock monitoring of the MAX20484 are fully demonstrable through the evaluation board hardware and the accompanying software. Figure 1 shows the block diagram of the EV kit.

The I2C communication is controlled using a Universal Serial Bus (USB) to I2C bridge that provides an interface between the IC and Graphical User Interface (GUI) which provides access to the MAX20484’ register set for configuration and status reporting.

Applications

  • ADAS
  • Autonomous Driving Processing Systems
  • Power System Supervision and MCU/SoC Monitoring
  • Remote Sensor Modules
