Hi Wang,
At page 28 of the User's Guide of DRV8825EVM shows that the DECAY pin can be connected to a potentiometer but it is not clear what its function is.
Regards,
Danilo
Hi Hide,
In most cases, using 1.5oz or 2oz copper and connecting to thermal pad is sufficient. The DRV8825EVM is an example of this.
We do not recommend heatsinks. You can find many by performing a web search for "smd heatsink" or "heatsink tssop"…
Hi John,
I used a Tektronix DMM4040 to measure the resistance on the DRV8825EVM.
In one direction (HI to V3P3OUT / LO to GND), the reading is 4.4kOhms.
In the other direction (HI to GND / LO to V3P3OUT) the reading is 3.5kOhms.
What equipment are you…

Hi Darren,
With proper heat sinking, the DRV8825 is capable of driving 2A at 36V. The DRV8825EVM is available to evaluate the operation of the device.
If 2A is full scale current, please also consider the DRV8880. This device includes AutoTune.
Hi jinlliang wu,
The recommended capacitor for V3P3OUT is 0.47uF. Please change it.
What value is the bulk capacitor on VM? There should be at least 10 to 20 uF capacitance on VM. The DRV8825EVM has 100uF.
Please monitor the VM voltage at the device…
Hi Gabriel,
This temperature may be difficult to achieve. I suggest obtaining a DRV8825EVM for evaluation. The PCB has large copper planes and 4 layers. If the EVM cannot achieve the desired temperature, a smaller board probably will not.
Rick Duncan said: Hi Griffin, The DRV8711 does not have this ability. The firmware can be used to track the steps issued to determine the home position. Please look at the DRV8825 . This device has integrated FETs and a home position indicator.
Thank…
