Overview

The EVAL-ADuM4177EBZ evaluation board is designed to demonstrate the features of the ADuM4177 high-current isolated gate driver, which provides 40 A source and 30 A sink peak drive capability. The board supports evaluation of advanced functions including SPI communication, slew-rate control, desaturation (DESAT) detection, Miller drive, active short-circuit (ASC), and temperature sensing. The document outlines power requirements for primary (4.4 V to 7 V) and secondary sides (15 V to 23 V), and details how to interface the board with the USB-SDP-CABLEZ for register configuration via the provided LabVIEW-based GUI. It also includes instructions for propagation delay testing, software installation, and detailed design resources such as schematics, board layout artwork, and a bill of materials.

Use Cases

  • Evaluating SiC power device gate driving performance
  • Testing gate driver slew-rate control and Miller drive functions
  • Configuring and programming ADuM4177 internal registers via SPI
  • Performing desaturation detection and active short-circuit testing
  • Measuring propagation delay in isolated high-current driver circuits
