TPIC2060A: 5V peak current

Satoshi Yone

Part Number: TPIC2060A

Hi, Team,

My cusotomer is using TPIC20060A and I have basic questions. They would like to decrease the peak current of P5V pin.
-Could you please let me know the reason of of the current?
-Is there any way to reduce 5V peak current?

Best Regards,

Hi Satoshi,

Thanks for your question.

May I ask, which driver is your customer using that draws the high peak current? And can you zoom in the scope capture?

The FCS/TRK/TLT outputs switch at 300kHz and I suspect that the high peak currents are from switching transients. Regarding the average current, 360mA is possible since the voice coils are typically ~10 Ohms and the output of the driver goes up to 5V. However, it is hard to know where this current is coming from without more information on the customer's application.

Best regards,
Grant
