Overview

The LMG3650 daughtercard features two LMG3650R070 650V GaN FETs with an integrated driver and protection in a half-bridge configuration with all the required bias circuit and logic/power level shifting. Essential power stage and gate-driving, high-frequency current loops are fully enclosed on the board to minimize power-loop parasitic inductance for reducing voltage overshoots and improving performance. The daughtercard is configured for a socket-style external connection for easy interface with external power stages to run the LMG3650R070 in various applications. Refer to the LMG3650R070 data sheet before using this daughtercard.

Features
  • Two TI 650V GaN in TOLL package arranged in half-bridge configuration
  • Digital isolators for high-side fault signal
  • Isolated bias supply and bootstrap supply option
  • Isolated gate driver and open component positions for layout compatibility to evaluate integrated GaN TOLL and discrete GaN TOLL
  • Heat sink with fan attached for heat dissipation during testing
  • Fault protection and reporting for over temperature, overcurrent and short circuit events
  • Standard daughter card pinout for compatibility with TI GaN motherboards
  • Absolute maximum voltage rating of 650V
Gallium nitride (GaN) power stages
