Hey Ahmet,
Can you measure the Vsystem 3.3V and 5V rails with a low battery to see if they are still stable 3.3V/5V even when the motors are spinning?
I suspect that your 3.3V rail is dropping out and the device is reading MODE as LOW. This switches it…
Part Number: DRV8410 Other Parts Discussed in Thread: DRV8213 Dear TI experts,
My customer tests DRV8410 for their new product. and they have a question about inrush current.
first they power power up DRV8410 and if motor is moved, I can see inrush current…
Hey Joel,
Agreed that it would be nice if our datasheet had this data. Unfortunately the best I can give you is another E2E post answered by someone more familiar with this part - https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers…
Hey Jennifer,
The DRV8251 operating voltage only goes down to 4.5V, so you would have to test whether 5V + PWM (maybe 55% PWM) could achieve the slow speeds. The DRV8251A gives current sense feedback via IPROPI, you could use that to implement some anti…
Other Parts Discussed in Thread: DRV8312 , INSTASPIN-BLDC Hi, I'm using the DRV8312 Piccolo kit. Investigations with the kit motor went fine but when I switched to a Faulhaber 3564 motor I noticed a behavior I can't explain. The speed seems to be limited…
