DRV8350: Does it is right soltuion to fight MP6570?

Hello Chen,

Short answer

It isn't a direct solution, they are related or adjacent. Try posting in the C2k forum about an instaspin enabled MCU.

Long answer:

Motor drive solutions need 3 parts, in general, to operate.

Controller ----> Gate Driver -----> MOSFETs

The controller contains algorithms like FOC or sinusoidal or trapezoidal. They usually output 6 signals that feed to the gate driver. The gate driver translates the 6 signals (usually PWM) and adds protection and translates them from a digital signal to an analog signal. The MOSFETs are... MOSFETs that deliver current by taking the analog PWM signals from the gate driver which is applied to gates of the MOSFETs.

The MP6570 is strictly a controller. A C2k instaspin FOC is a strict replacement but there are still differences between fixed function (MPS) and open core (C2k): https://www.ti.com/microcontrollers/c2000-real-time-control-mcus/products.html#p2192=InstaSPIN-FOC%20Technology;InstaSPIN-FOC%20technology 

The DRV835x family is a gate driver so you would also need ti FET (like the CSD88599Q5DC) to compete with MP654x device which is a Gate driver + MOSFET integration.

Something like DRV10x integrates all 3, controller, gate driver, and MOSFET but isn't a suggested solution to replace the MP6570. 

As such, the C2k is your best bet but ti still has a portfolio gap for something that is an exact replacement for the MP6570.

Hello Chen,

Thanks for the update. Yes, I'm not surprised they want something simpler. Unfortunately, this a known portfolio gap as we discussed. I don't think there's anything else we can offer.

Keep an eye out later this year, we might have some more things coming that would be able to compete with this.

Best,
