Part Number: DRV8825 Hi Team
Customer are using our DRV8825 to drive a stepper motor which spec show as following. and the VM=24V, I_Chop=2A, 1/32microstep. When it works at 4000 step(1.8°)/s, the phase current show as following, and there is distinct noise…
Part Number: DRV8825 Hi, support team
My customer has the questions as follow:
We are designing a PCB to control three stepper motors and a spindle motor in a CNC mill/engraver.
Each stepper motor will be controlled with one T.I. DRV8825 IC.
We would…
Part Number: DRV8825 Other Parts Discussed in Thread: , DRV8424 We have a prototype circuit board which uses the DRV8825. We have found that current control is lost when current setpoint is < 700mA. For example, a setting which we expect 200mA will actually…
Hi All,
I think PCB layout may need some improvements. Taking a look at picture above (I assume PCB is 2-layer one) I noticed a few errors like:
- thermal vias under DRV8825 have thermal reliefs,
- C5 grounding trace is long (high inductance), C5 could…
Part Number: DRV8825 Hi,
i am evaluating DRV8825 for my application with motor spec (24V ±10% current: 1 phase 0.6A, 2 phase: 1.2A), planning to use in 1/16 OR1/32 mode
i have adjusted Vref. to 0.685V, now i am able to drive the motor correctly…
Part Number: DRV8825 Dear Support,
Here are my schematic design using DRV8825:
I faced strange behaviour as described below:
1. Good one show the peak current is at 1.64A
2. Faulty one, noticed peak current has halved, seems the output current is not…
Part Number: DRV8825 Hi Team,
1. In the Fstep of the timing requirement, I want to confirm whether it is a PWM clock, so the requirement for DRV8825 is below 250Khz? 2. As shown in the diagram, is the step size controlled by mode 0~3? Signals and controls…
