Part Number: DRV8811 Hi,
My customer has a problem. Some DRV8811s cannot regulate the motor current correctly at setting small chopping current. Please see the below waveform. Waveform1 is incorrect case. Waveform2 is correct case. These waveforms are…
Part Number: DRV8811 Hi,
Our customer has been testing the DRV8811 with a stepping motor. He has observed the current of motor windings. The waveforms of the current is as follows.
There are spike noises on the current waveforms.
I have some questions…
Part Number: DRV8811 Hi,
Our customer would like to use the DRV8811 with a DC motor.
They have some questions.
- Does the DRV8811 get damaged in the following cases?
Supply voltage;
1) only VM without Vcc
2) only Vcc without VM
- Can the…
Other Parts Discussed in Thread: DRV8811 Hello,
I am using DRV8811 to control a motor. I am applying 3.3V to STEP pin for 50us and 0V for 9ms. After some revolutions of motor the DRV getting too hot, it stops the motor like glitches. I have copied the…
Hi,
I have been working on this IC. My query regarding this device is that how does maximum value of chopping current is set? according to functional block diagram in datasheet the Rsense connected between ISENA/ISENB and Ground must be playing role…
Other Parts Discussed in Thread: DRV8811 We got some customer technical question.
In DS Pg.7, we can check the timing diagram and definition of each time spec.
In 6, wake up time spec, what does it mean of this?
In sleep mode operation…
Other Parts Discussed in Thread: DRV8811 Hello,
I am using DRV8811 in my stepper motor driving application. I have successfully driven motor also. but problem with my driver circuit is Vcc and ground pin of driver are getting shorted after some time…
Other Parts Discussed in Thread: DRV8811 Can anyone explain how does reset pin and sleep pin differ from each other in drv8811???... And also use of all enable sleep and reset pins??
