Part Number: DRV8874EVM Other Parts Discussed in Thread: DRV8874 Hi team,
Can DRV8874EVM be used to drive stepper motor?
If it can do that, how should I need to modify the EVM?

Part Number: DRV8874EVM Hello experts,
I just want to clarify a little thing about DRV8874EVM.
In the EVM schematic, there's 10k resistor(R14) connecting to the nFAULT.
However, nFAULT looks like connecting to the MCU through the jumper on the EVM…
Hi Antenna,
The dead-time is the time inserted when one half-bridge is switching from High-side to Low-side or vice-versa. During this period, current flows through the body diode of the FETs. The purpose of adding this dead time is to prevent a cross…
Willie,
Is it possible to order a sample from the DRV8874 ?
DRV8874 sample can be ordered from https://www.ti.com/product/DRV8874
Is there a small PCB for/with only the DRV8874 and components, so without the uProc like the DRV8874EVM (evaluation module…
Ryan-san,
We have confirmed that the DRV8874EVM works as expected.
However, simulating with the same settings will give different results.
The model is different from the actual behavior.
Please correct the spice model.
Best Regards,

Thank you for your response Pablo. At the moment we don't wanna apply an LC filter, though it will become interesting in the near future. Is there an alternative to the DRV8874EVM featuring a higher output voltage then 37V? We would need smthg in the…
Hi Subbaraju,
Conceptually, this appears to work.
May I suggest you experiment with a DRV8874EVM?
There are two methods available:
1) Disconnect the mcu on the EVM and control the DRV8874 with the mcu of your choice. 2) Re-program the mcu on the EVM. This…
Hi Ziqi,
Are you utilizing the DRV8874EVM? If so, is it modified in any way?
Can you go through the faults the DRV handles to check if you go below the VM's UVLO, the VCP's UV, or above the OCP? Finally, is there anyway for you to measure the temperature…
