EVM User's Guide: BOOSTXL-LMG2100-MD
BOOSTXL-LMG2100-MD Evaluation Module
Description
The BOOSTXL-LMG2100-MD Evaluation Module,
also referred to as "EVM" throughout this document,
implements a GaN inverter with precision in-line
shunt-based phase current sensing for accurate
control of precision drives such as servo drives.
The EVM offers a TI BoosterPack
interface to connect to a C2000
development kit for easy performance evaluation.
For more test results and other technical information
please refer to TIDA-010936.
Applications
•
Robotics (cobot/AGV/humanoid robot)
•
Servo drives and motion control
•
Computer numerical control (CNC) drives

Features
•
Wide input voltage range 12V to 60V
•
Compatible for LMG2100R044 and LMG2100R026
•
GaN half-bridge power stage simplifies PCB layout
and reduces parasitic inductances for optimized
switching performance

Compare with MOS solution, TI GaN reduces
>50% size
•
Precision in-line phase current sensing with 1mΩ
shunt (for theoretical ±33A full-scale range)
•
This board can run up to 15.6A_RMS
(LMG2100R044) or 24A_RMS (LMG2100R026)
without heatsink, and is heatsink compatible
•
TI BoosterPack compatible interface with 3.3V I/O
for easy performance evaluation with C2000 MCU
