BLDC motor driver recommendation

Hi Pooja,

We have many sensorless BLDC motor drivers. Please advise what kind of specification you are looking for. I recommend looking at the BLDC Motor Driver Selection Guide for a better understanding of the specifications you can look for in a BLDC motor driver: https://www.ti.com/lit/pdf/slvaes1

If your motor is <100W and control is integrated into the driver, I would recommend looking at the MCT8316A, MCF8316A, or any device in the DRV10x family for integrated control and MOSFETs. 

If your motor is <100W and control is provided via MCU, I would recommend looking at the DRV8311 or DRV8316 for integrated MOSFETs. 

If your motor is >100W, you'll need a gate driver device with integrated CSAs, so I would recommend looking at the DRV8323, DRV8323R, DRV8353, DRV8353R, DRV8343, or DRV8305. 

Thanks,
Aaron

Hi Pooja, 

Thanks for the additional information - in the case where you want a sensorless BLDC driver and some mechanism to identify rotor position at standstill, 

Some parts I can recommend are: 

• DRV10983, DRV10983-Q1, DRV10975, and DRV10987

You may want to check if the operating voltages and general specs of these devices are sufficient for your system needs. 

However, an example of the feature you are looking for would be 'Initial Position Detection' or IPD. 

I've attached two resources below for you to look at this further:

Thanks and Best Regards,
