Other Parts Discussed in Thread: TEST2,
Hi Team
Our team are testing the DRV2511 with DRV2511-EVM.
All the default of the evaluation board were working successfully.
TEST1.
After that, our team modified the
Gain setting from 20dB to 32dB,
capacitor of RC filter between PWM port of MCU and IN port of DRV2511 from 0.22uf to 22nf.
And, we introduced an external PWM signal whose frequency is 50KHz to create a sine waveform, then that went greatly.
TEST2,
, we tried to operate DRV2511 without default MCU in EVM board.
The processes that we have done is below:
applied 3.3V to EN port of DRV2511 directly from a external voltage supply.
pulled down the STDBY, FS1, FS2, FS3 to 0V
then, we introduced the same PWM signal as last.
We found the voltage result after RC filter are lower (about only half of TEST1) than TEST1.
Could you teach us, whether there are any other condition or setting to operate DRV2511 correctly.
Best regards.
