I have a question regarding the MP6540HGU-A motor driver.
It was stated on another topic that the maximum response frequency of its built-in current-sense circuitry is 100 kHz.
Can you state which criterion for the signal amplitude/distortion was used to determine that as a cutoff frequency? All I can gather from that topic is that in that case the IC stops working since it enters the OTP condition.
So in reality, the usable bandwidth is less than 100 kHz?
Is the 100-kHz frequency the -3dB point, i.e. what is the current-sense ratio at that frequency?
Is it possible that we get the full amplitude-frequency characteristic (variation of the current-sense ratio as a function of frequency)?
I hope you can help me with this inquiry.
