Part Number: DRV8461 Other Parts Discussed in Thread: DRV8711 Tool/software: Dear Support Team. We are investigating whether our customer can set the current limit value of the DRV8461 arbitrarily. As far as I read in the data sheet, there is no resistor…
Part Number: DRV8461 Dear team,
Can I know the difference between Microstepping vs. Automatic Microstepping?
This is my understanding, please correct me if I was wroung.
Microstepping is set by MICROSTEP_MODE register up to 1/256. - It divides the motor…
Part Number: DRV8461 Does the placement of an external sense resistor affect the PWM current regulation?
Also, what is the resistance value of the internal current detection?
Part Number: DRV8461 Hi team,
I have a customer with the below question. Let me know what you think and thanks in advance for your help!
"Please explain how to use DRV8461 INDEX4/INDEX5 registers to calculate coil A current. What current in amps does…
Part Number: DRV8461 Other Parts Discussed in Thread: DRV8462 , Since the DRV8461 and DRV8462 are drop-in compatible, would firmware developed for one of them work for the other?
Part Number: DRV8461 Hello guys,
One of my customers is considering using DRV8461 for their new products.
They have the following questions about switching loss calculation as the follows. Could you please give me your reply?
Q1. 30kHz is used as PWM switching…
Part Number: DRV8461 Hi Dear,
Referring to the evaluation board of DRV8461, it is necessary to monitor the AOUT1/AOUT2/BOUT1/BOUT2/VM voltage,which requires 5 ADC interfaces. as shown in the following figure.
However, the built-in ADC peripheral resources…
Hello Elavarasan,
For stepper currents > 3 A the following drivers are a good fit, DRV8452 5 A IFS (I full-scale) in DDW-44 package ad 4 A IFS in PWP-28 package. Other devices such as the DRV8461 and the DRV8462 are also a good fit. The DRV8462 in DDW…
Hello Ethan,
Please refer to the EVM User's Guide https://www.ti.com/lit/ug/slou558b/slou558b.pdf pages-40 to 42. You can remove the jumper shorts for J4 and J8 and for the VREF. Then you can access the DRV8461 pins via the header and connect it to…
