I'm currently in the feasibility stage of design and hit a bit of a snag. I'm designing a potential merch item / toy for a FRC team I work with and I want to implement a PCB based Brushless motor. This would be given away at competitions as a DIY kit so the total BOM price will make or break if I should even make a prototype. I know the reputable brands have their place and are worth their prices, but in my head I have to imagine there is an extremely cheap all in one solution that is on the order of ~$0.50 or less in the Asian market. As far as requirements other than cost, I need it to take in PWM speed control, hall sensors (Low speed control required), and direction as inputs and output directly to the PCB coils. Ideally in an SOIC package as I would like this to be accessible for beginners to solder. The closest chip on digikey that checks most of the boxes is the BD63282EFV-E2 from Rohm, it's a tssop but otherwise has everything I want other than price. The closest chip I found that might work is the JY01 from a company called JUYI. I can get it for $0.69 from Alibaba at quantity 100. This chip however still requires external mosfets, driving up the bom count and cost and is still a bit more expensive than I would like.
I wanted to ask and see if anyone knows of a cheaper all in one driver IC that meets the requirements above or at least comes close. If we ended up making it, would probably get 100-200. Western friendly sellers like LCSC and Ali would be a nice touch as well.
