Hi Nivant,
On our EVM, the MSP430 MCU is generating the PWM by taking the analog input from the potentiometer.
Please review our MCT8316ZEVM design files tab to view the EVM schematic: https://www.ti.com/tool/MCT8316ZTEVM#design-files

Part Number: MCT8316Z-Q1 Other Parts Discussed in Thread: DRV10970 , MCT8316Z , MCT8316ZTEVM , MCT8316A That being said, your document about tuning with this motor controller needs to be revised, almost needs to be totally rewritten. It seems to apply…
HI
The issue is that i dont know .. i would like to order EVM
https://www.ti.com/tool/MCT8316ZTEVM#order-start-development
but the problem is that is not availabe .. so i can not test.
Do you have any idea when it will be back on order ?

Hi Randy, I checked on the MCT8316ZTEVM in the lab and confirmed that the default setting for FGOUT_SEL = 0b00. FGOUT frequency is 3x the commutation frequency. So the real RPM is equal to (3*3*(60.5/60)) = 9.075 times less than what is reported on the…
Hello Victor,
Have you looked at MCT8316Z? This part offers sensored trapezoidal control with integrated FETs (drives up to 70W) and without any SPI communication necessary. The motor speed is controlled through the input duty cycle. We do have an EVM…
Hi Jayam,
The motor driver IC does get hot, since there are many integrated features in integrated BLDC motor drivers such as:
- 6x MOSFETs (conduction and switching losses) - AVDD linear regulator - Buck regulator - Standby current
However the…
Hello Sayali,
Thanks for the info. I believe that the MCT8316Z will be a good fit for your application.
Some features include:
40V max
8A peak current
Trapezoidal control
Sensored control
and is also 1xPWM like the DRV10970
This is a…
Hello DJ, I tested on MCT8316ZTEVM and see a minimum duty cycle resolution of about 0.1% at 20kHz. 5% duty cycle @ 20kHz should equal OUTx on period of 2.5us (50us * 0.05 = 2.5us). I used a 5% PWM signal and measured 2.5us on average at OUTx output. Then…
Hello Randy,
Sorry for the delay on your question. MCT8316Z should be releasing to market in about a day or two, you can sign up for updates on the website to find out when stock becomes available. You may also order prototype parts if you click on…
Hi Chase, MCT8316Z0T and MCT8316Z0R are available for APL currently. Looking at samples.ti.com, I see you can sample MCT8316Z0R only or MCT8316ZTEVM . Both will be released to market near end of August.
For now, we recommend evaluating with MCT8316Z0T…
