TMCS1100: tmcs1100

Part Number: TMCS1100

How do the typical equipment set up and connections look like for plotting sensitivity vs frequency (fig 7-9) and phase vs frequency (fig 7-10)?  I am interested to know how much curent value was used compared to the max rating of 30A for this IC?

    swetcha,

    I am looking into this, but the engineer who supported these tests is out for the day. I will check in with him and will provide an update on Monday.

    swetcha,

    Sorry for the delay here. This data took a while to run down. 

    The engineer's main intent was to have a small signal on the output, as to not slew rate limit the results. They used a 200mV output, so the input signal is that value modified by the sensitivity. So for example, for the A1, 50mV/Amp = 4 Amps, and for the A4, 400mV/Amp= 0.5 Amps.  

    The data for both this capture as well as the phase capture was performed using a BODE100. 

    Please let me know if you have further questions.
