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…
Hi Jason,
This is not device specific. This is because of insufficient VM voltage to overcome the back EMF generated by the stepper at those speeds resulting in phase currents not reaching target value for proper current regulation and wave shaping. This…

We planned to use TI’s Stepper motor driver because we are having a few quires.
We are using “SMS6-F40” and "SMSH8-F40”…
Hi Junho,
To reduce the current in hold position to manage the thermal dissipation in the drive coils VREFO should be reduced to a corresponding lower value. Customers do this using a resistor controlled by an MCU GPIO or using a DAC or PWM DAC output…
Other Parts Discussed in Thread: DRV8452 , DRV8434S , DRV8434 , DRV8462 , DRV8461 I want to use a CNC machine to wirelessly control a stepper motor, but the problem I encountered is that the CNC machine cannot be connected to Modbus. Do you have any solution…
Hey Tony,
I recommend the DRV8452 or DRV8461 . These have a similar package to the TMC2226 and better performance specs. A smaller more budget-friendly option is the DRV8425 .
Here are all our stepper drivers filtered for >29V and >=2A full-scale RMS current…
