Hi Gregor,
No worries. I interpreted the datasheet description and made that statement.
You said, " also because we're operating many many DRV8801 at 12V and none has the nFault triggered...". Thanks for sharing this information.
This was why I…
Hi Farinaz,
If you intend to control the speed of the motor, the PWM generator should be connected.
The PWM signal is typically connected to the ENABLE pin.
Please refer to the DRV8801EVM as an example.
Other Parts Discussed in Thread: DRV8801EVM Hi
I am using DRV8801EVM and sense resister changed from 0.2ohm(default) to 2.2ohm. I meet issue when VBB voltage is supplied to EVM. Issue is nFault is every time Low out put when VBB voltage is supplied…
Bobby Lam said: does this driver require a microcontroller?
No. It just requires a direction signal and a PWM input source for speed control. Both of those can be accomplished without a microcontroller.
However, that being said, there is a DRV8801EVM…
Hi Suraj
First, I would like to introduce the TI EVM http://www.ti.com/tool/drv8801evm for your reference on both hardware and control software. You can download the design package including everything under that page.
Then, for a normal DC motor…

Although I still need to use power line to transmit the data about the motor's speed or something else to control the motor.
So, do I need to buy a new device or any software I can use?
if you wish implement motor control…
