DRV8332: find a Commutator IC beside DRV8332

Part Number: DRV8332
Other Parts Discussed in Thread: DRV8306

I have a BLDC motor with hall effect sensor and I have to design a driver for it.

I want to use DRV8332 IC for drive my BLDC motor but I don't want to use my MCU for commutation step. I want to make duty cycle with my MCU to control the speed of motor and give commutation to another IC. I found DRV8306 IC that is excellent for my need but I can't match it with DRV8332 because of voltage level differences. I don't want to use MOSFET or half bridge with DRV8306 or maybe level shifter.

I want to know does it exit any IC to do commutation and doesn't have MOSFET driver on it like DRV8306.

I would be thankful if you could help me to find a IC beside DRV8332 to do my job.

Hi,

We currently do not have a driver with integrated FET's + Control. This is only available in gate drivers.

thanks for your response

I don't need a driver with integrated FET's + Control. I just need a IC do commutation step (control). IC like DRV8306 but with TTL output that could be connect to DRV8332.

Amir,

We do not have any devices like this, my apologies.
