L6230 - simple BLDC driving with BEMF detection

Tomá¨ Mat?jka · ‎2019-05-14

Hello, I want to use l6230 for BLDC motor driving. I'm trying to use it in typical application from the attached picture.

In this application is commutation drives through binary signal from CPOUT - zero crossing.

Is commutation drives through a binary signal from CPOUT in this application?

Is intended to continue at the six-step sequence when CPOUT is active?

How can i choose resistors R1, R2 (or R3)?

I want to drive standard BLDC motors for drones 12N14P, Example Motor

Thank you for your answer 🙂

i found this document containing some details similer to you are asking for

https://www.st.com/resource/en/application_note/an4243-l6230-dmos-driver-for-threephase-brushless-dc-motor-stmicroelectronics.pdf

can you please do the calculation part and put a detailed connecection diagram.

thanks in advance.🙏

Uhm - do you realise that you have answered a 5 year old question? The TO probably no longer needs a solution.
