Overview

LMG3522EVM-042 configures two LMG3522R030 GaN FETs in a half bridge with the cycle-by-cycle over current protection, latched short circuit protection function and all the necessary auxiliary peripheral circuitry. This EVM is designed to work in conjunction with larger systems.

Features
  • Input voltage operates up to 650 V
  • Simple open loop design to evaluate performance of LMG3522R030-Q1
  • Single/dual PWM input on board for PWM signal with variable dead time
  • Cycle-by-cycle over current protection function
  • Convenient probe points for logic and power stage measurements with oscilloscope probes that have short ground spring probes

  • Attached heatsink with fan
Gallium nitride (GaN) power stages
