Other Parts Discussed in Thread: DRV8824
Dear Sirs,
My customer test EVM to drive EEV and found some questions as below.
1. nENBL control issue:
While DRV8824 into disabled mode(nENBL is high), the output pin waveform as below. Is it normal? Will it case any question for control?
2. current regulation issue:
It seems the current regulation start from 0.188A, and the Max current measured was 0.272A, not up to 0.3A. Is it correct or not?
My understanding is, once the current up to 0.3A(current chopping threshold), current regulation will start, is it right?
3. Decay mode issue:
Is the PWm frequency is 16KHz as below photo item1?
What is the reason of the waveform of item2? Is it correct or not?
The detail issue description is in attached file.
Please help!
Thanks.
