DRV8316C-Q1: I need a simple bldc motor controller

Part Number: DRV8316C-Q1
Other Parts Discussed in Thread: DRV8316C, DRV8316

For my project i am looking fo a simple 3-PWM bldc motor controller, during my reacearce drv8316c did look like one of the best options.

The problem I have with this schematic is the fact that AVDD is beeing used (onboard LDO) but I dont want to use this one.

Is there a standard schematic witch includes the following?

Input: U, V, W, sleep and maby enable

Output: OUTA, OUTB, OUTC

Hey Wessel,

Have you looked into the DRV8316 EVM?

This link contains downloadable HW files that can be used as a reference.

Hey Akshay,

Thank you for the response, but i only see the pin 6PWM mode.

I explicitly look to controll te motor by 3-PWM mode.

I also need to make a PCB so ordering this board makes no real sense.

Greets,

Wessel

Hey Wessel,

Yes, our EVM uses 6x mode with the FW, but it can be a good resource to see how we have connected the sleep and enable and other pins.

I do not believe we have a 3x mode board to show as an example but the logic of the 3x mode from the datasheet can be used a basis for designing your own board.

Best,
Akshay
