Part Number: DRV8889-Q1 Tool/software: Hello, I'm running a step motor by manufacturing a PCB using DRV889 products. But I'm worried because of the frequent degeneration phenomenon. I describe it as the time required to drive the motor by not giving…
Part Number: DRV8889-Q1 Tool/software: Hi,
Are you able to confirm whether the DRV8889-Q1 uses Bipolar/BiCMOS technology at all? I'm planning on doing some radiation testing on this part, and the technology type will influence the dose rates I test…
Part Number: DRV8889-Q1 Tool/software: hi expert,
When the motor is in stall status , can DRV8889-Q1 detect how many steps are lost, customer hope to use this function to do closed loop control
Part Number: DRV8889-Q1 Tool/software: Hello expert,
I am using the motor chip DRV8889. The application scenario is the stepper motor of the car light. I have a few questions to confirm:
1. How to arrange the wiring harness when the chip is connected…
Part Number: DRV8889-Q1 Tool/software: Hi Team,
There is a VSDO to power SDO for DRV8889-Q1. We are connecting this to an external 5V. Based on this, we would like to know what is the SDO's VOH min voltage, is it ~4.1V like other DRV devices? Will it…
Part Number: DRV8889-Q1 Tool/software: Hi Murugavel ,
I used DRV8889-Q1 to drive the 14HK0405 stepping motor, and found an issue. The test conditions were as following:
Decay mode: Smart Tune Ripple Control
When the motor stopped, sometimes I could…
Part Number: DRV8889-Q1 Tool/software: As I saw DRV8889 data sheet, the motor current can be adjust by VREF and TRQ_DAC value.
I have 3 questions
1. Minimum voltage of VREF
2. Minimum current
3. Is No3 or No4 case possible?
No
VREF(V)
TRQ_DAC

Part Number: DRV8889-Q1 Tool/software: Our company has newly evaluated the customer's HUD project and requested that the bipolar stepper motor drive have the ability to detect locked rotor. After reviewing the drv8889-q1 specification, it can be understood…
Part Number: DRV8889-Q1 Tool/software: Hi team,
For DRV8889A-Q1, does it work at low temperatures of 40 degrees? The customer has found that the chip is currently unable to drive at low temperatures of 40, could you please help analyze the possible cause…
Part Number: DRV8889-Q1 Tool/software: Hi team,
Customer did OCP test in BOUT1 pin, which is shorted to GND, and they found that BOUT1 is shut down (output current is 0), while the BOUT2 current waveform is:
Red is BOUT2 current, green is nFAULT pin…
