Part Number: CSD19501KCS Hello, TI team.
Thanks a lot to your team for sharing so many valuable design reference documens.
I am studying "MOTOR-DRIVE-FOC-FET-LOSS-CALC" for cross check MOSFET power loss.
Some calculation equations confuse me…
Part Number: CSD19501KCS Other Parts Discussed in Thread: MOTOR-DRIVE-FET-LOSS-CALC , Hi, In the MOTOR-DRIVE-FET-LOSS-CALC Excel sheet, the equations tab contains an equation to calculate RDS(on) with temperature. But I am unable to understand what ΔRDS…
Part Number: LM5069QUICK-CALC Other Parts Discussed in Thread: LM5069 Dear team,
I'm using the LM5069 Design Calculator with FET Recommendation for SOA calculation
However Some of the green cells in the calculator is invalid.
1. can't set the load…
Hey Craig,
craig Garvin said: Are there any SPICE models that you would recommend as a starting point to model this part?
Unfortunately there isn't anything great. DRV8412 is unique with a bootstrap architecture vs the charge pump found in most of…
Hi Daolin & Pekka,
Thanks for your explanation in details!
Customer recently has retried this experiment. They have done the below 3 testing based on SDK9.1 RT Linux.
1: Run Codesys ethercat on AM64x only (not connecting to am24x), the servo motor…
Hi,
For 5-wire type only full-step must be used. It is not a driver limitation. It is a limitation of how the motor windings are wired in 5-wire unipolar motor and while using it with a bipolar stepper driver.
You could use use half-bridge driver, for…
Hi Annie,
To monitor speed, it is better use FG signal which is more Realtime data. The GUI refresh at slower pace,
Can you provide motor parameter, rated voltage, rated speed etc.
Also, I believe the Resistance, Kt are measured as mentioned in the tuning…
Hi,
Thank you for your questions.
1) Over current protection.
You mentioned 10A@0.5msec. One possibility is hitting OCP. If we capture the OUTx pin output current waveform with zoomed-in (like 10us/div) single-trigger with nFAULT pin low, peak current…
Part Number: DRV2510-Q1 Dears,
The customer has been using DRV2510 to drive Handeli's motor and has been experiencing some abnormal noise. They would like to consult with you on the usage of DRV2510. The peripheral circuit is as follows, thank you!…
