Hi Yara,
Thanks for your reply. These days I optimized the measurement method, reduced the IDRIVEP/N current from 2.0/1.0A to 0.16/0.08A, and then optimized the ringing. Although the ringing still exists, I will try to optimize the circuit to reduce the…
Part Number: BOOSTXL-DRV8320RS Other Parts Discussed in Thread: LAUNCHXL-F280049C , DRV832X Hi,
I am planning to use BOOSTXL-DRV8320RS and LAUNCHXL-F280049C to control a PM motor in a back to back motor-dyno configuration. So, I will need the inverter to…

If I add 1us software deadtime from MCU between Vinhx and VinLx like below picture.
and DRV8320's hardware deadtime is 100ns.
then What is the total deadtime between…
SeungGeun Yang said: 1. Looking at other users' forums about PWMDAC Module, is it true that EV Board(280049+drv8320) cannot use the PWMDAC Module?
There is not a RC filter on Launchxl-f280049 for PWMDAC.
