EVAL-ADuM4122EBZ User Guide: Evaluating the ADuM4122 Single Gate Adjustable Slew Rate Isolated Gate Driver
User guide for the EVAL-ADuM4122EBZ evaluation board, featuring the ADuM4122 isolated gate driver with adjustable slew rate and 3 A short-circuit output capability.
Overview
The EVAL-ADuM4122EBZ evaluation board facilitates the evaluation of the ADuM4122 isolated gate driver with adjustable slew rate control. Utilizing iCoupler technology, the board provides isolation between the input signal and the output gate driver. It features pad placements for TO-247, TO-252, and TO-220 power devices, such as MOSFETs and IGBTs, and supports output voltages up to 35 V. The design allows for two selectable slew rates via external series gate resistors and jumper configurations on the SRC pin. Additional features include screw terminals for connectivity, bypass capacitors, and support for both unipolar and bipolar voltage configurations to simulate various driving conditions.
Use Cases
- Gate driver propagation delay and drive strength testing
- Evaluation of adjustable slew rate switching performance
- Characterization of MOSFET and IGBT power devices
- Isolated power supply and driver system prototyping
- Capacitive load testing for gate driver outputs
