Hi Team,

In one of our product we need to drive a BLDC motor which operates 15 to 22V supply. for this we need a driver ic. I was gone through you web site i found some ICs like DRV8306 which is need an external micro controller. I need a driver IC with micro controller is there any part like so.

Thanks

Ashok,

Thanks for posting on the MD forum!

If I understand your question, you would like a motor driver IC with integrated control and MCU?

What is your maximum motor current?

Regards,

Ashok,

I would suggest using the DRV8323, this device can accept hall sensor inputs and will not require an MCU.

Please check the EVM here: http://www.ti.com/tool/BOOSTXL-DRV8323RH

You can look into the documentation for the Sensored code also: http://www.ti.com/lit/ug/slvub13/slvub13.pdf

Hi Adam,

Good Day to you...!

DRV8323 doesn't have controller inside. I need controller as well with driver IC to control other peripherals like LED blink, ADC...etc

In TI such kind of IC is there? or I have to go with separate controller and separate Driver IC.

Thanks

Ashok

Ashok,

Unfortunately we do not have any drivers with a general purpose MCU inside the same IC which support your power level.
