Part Number: DRV8411A Tool/software: Hi,
1. Does a leak current flow through the VREF pin?
2. Does VREF have any effect when switching to low-power sleep mode? I would like to confirm whether the VREF pin must be powered off during low-power sleep m…
Part Number: DRV8411A e2e,
I´m currently looking for a stepper motor driver to drive a plunger which must exert a defined force to the front of the valve pin and makes a reference run to the rear to detect the position. In addition, it would be desirable…
Part Number: DRV8411A Other Parts Discussed in Thread: DRV8412 Hello,
We are worried about the maximum PWM frequency of 100kHz indicated in the datasheet, could you please give me detail about this limit? Why is it limited? is it related to the INx input…
Part Number: DRV8434S Other Parts Discussed in Thread: DRV8411A , DRV8411 Hello team,
On the datasheet, fullscale current is set by TRQ_DAC.
My customer would like to know how is the full scale current is regulated by current sense block, opamp, Kv and…
Hi Ryan,
I'm going to neutralize the comparator in the DRV8411A, and use the comparator in the microcontroller. I'm going to tie the VREF pin on the DRV8411A to +3.3V, and use a lower threshold voltage in the microcontroller. Then the comparator…
Hi Basit,
Basit Ali Khan said: Need to find a driver for 28BYJ-48 stepper motor, which driver will be most suitable. I need the driver with stall detection feature but most driver ICs that I am finding uses bipolar motors but 28BYJ-48 is a unipolar motor…
Hey Webber,
That's pretty much all of it. The DRV8834 is one of our older parts, you might want to look at something newer like the DRV8411A with improved current sense accuracy and regulation.
Regards,
Jacob
Part Number: DRV8912-Q1 Other Parts Discussed in Thread: DRV8889-Q1 , DRV8411A Hi team
Can DRV8912-Q1 drive a two-phase stepper motor? As shown in the picture.
Other Parts Discussed in Thread: DRV8251A , DRV8251AEVM In some applications, it is important to know when a motor stalls due to an obstruction or reaching the end of travel (for example a door lock reaching the final locked position). This FAQ will discuss…
