Tool/software:
Hi,
We are currently evaluating the TPSF12C1 active EMI filter IC, and would appreciate your support regarding the following technical questions:
[Question 1]
What kind of processing or behavior does the TPSF12C1 perform in response to noise components entering via the SENSE capacitor? Could you kindly explain the internal signal detection and waveform generation flow, as far as is publicly available?
[Question 2]
Is it correct to understand that the output waveform frequency at the INJ pin changes in response to the frequency of the noise components observed at the SENSE pin?
[Question 3]
If multiple noise frequencies (e.g., ①,② and ③) are present at the SENSE input simultaneously, can the TPSF12C1 actively cancel both components? Or is it limited to reacting to a single dominant frequency?
[Question 4]
Previously, we received guidance on E2E that when the amplitude of the INJ pin is close to VDD, it may indicate saturation. Could you provide a more concrete numerical threshold or waveform example that distinguishes between saturated and non-saturated operation? If possible, please also explain the internal limitations that lead to saturation.
Best regards,
Conor
