Hello all,
I am using the MCT8316ZT (hardware variant) on my PCB to drive a BLDC motor. I am still in the first stages of testing but have hit a bit of a snag. The problem is, I am feeding a PWM signal into the motor driver, along with a direction, but the motor driver seemingly does nothing. The motor does not move at all, and the current draw into the system remains unchanged (0.02 A).
Currently I am combing through the datasheet to make sure my external components are correct and that I am configuring the device correctly. I also plan on confirming that the device is soldered on correctly and everything is correctly connected.
However, this is my first time using a device like this so I would like to inquire if anybody else has had similar problems?
My driver schematic is attached. I have not shown how I connect Slew, Advance, Mode, and ILIM. I have simple resistor networks that bias these pins according to the specifications I am looking for.
Additionally, the driver model is actually the SPI variant, but I made sure to substitute the hardware variant pins for the SPI pins by looking at the datasheet.
Thank you!
