HI

Looking for experience with the A8904 BLDC controller.

My motor dose not have CENTER tap required for the BEMF connected to PIN 10

Can I connect a 3 phase motor without the center tap - how to do it?

Should i add a BEMF comperator stage for detecting the zero-cross BEMF signal?

Any one hase some advice or for working experience with that chip?

Any one has software rotuine for programming and operating the chip?


Thanks in advance

Bobi
