LMG3100R017: Component Selection and Current Rating Clarification

Tool/software:

Hello,

I am a beginner engineer working on a motor drive design and would appreciate your guidance on component selection and specifications.

My Requirements:

• Input voltage: 48V DC
• Continuous operation: 30A RMS
• Peak operation: ~80Apeak for approximately 3 seconds
• Application: Motor drive system

Questions:

1. I am considering between LMG3100R017 (126A rating) and LMG3100R044 (46A rating). Which would be more suitable for my application requirements?
2. I plan to base my design on the TIDA-010276 reference design. Is this reference design appropriate for my specifications?
3. Current Rating Clarification: Regarding the LMG3100R017's 126A specification - can you confirm this is the RMS current rating? I want to ensure I understand the datasheet correctly for proper thermal and electrical design considerations.

Thank you for your time and assistance.

Best regards,

Han.
