Part Number: DRV8452 Other Parts Discussed in Thread: DRV8434 I am trying to initialize the DRV8452. As I understand it, activating the EN_OUT bit in the CTRL1 register over SPI is mandatory for this.
As a first SPI test, I read back the FAULT, DIAG1…
Part Number: DRV8452 Good day everyone I'm experience the following issue with this driver : Configuration #1 12V VM, 3.3VCC, ~0.6mH winding inductance, VREF = 3.3V/2, SPI mode, all registers at it's default settings no microstepping, when enabling output…
Part Number: DRV8452 Other Parts Discussed in Thread: INA187 Dear Technical Team;
I am using the DRV8452 to drive a bipolar stepper motor in a medical device application. The motor operates in microstepping mode, and I would like to monitor the motor…
Part Number: DRV8452 Hello,
There is a question from a customer about Non-Circular 1/2-Stepping Current shown on the Table 7-9 in the datasheet, as below.
It seems this table shows the DIR=1 case, but can this be used for DIR=0 case, as well?
…
Part Number: DRV8452 Hello T.I. Teams ,
in the DRV8452DDWR these is a nHOME pin that is an Open Drain .
If it is not used , it can be left unconnected or is still a best practice to connect to Vcc via a Resistor ( e.g. 10k ) ? Thanks
Maurice
Part Number: DRV8452 Tool/software: Hi experts
We are considering the use of the motor driver "DRV8452DDWR." We plan to connect it via a daisy chain using SPI communication, where the "STEP" signal will be input from the microcontroller to each motor…
Part Number: DRV8452 Other Parts Discussed in Thread: DRV8462 , DRV8462EVM Tool/software: Hi team,
Do not seem to have an EVM for DRV8452, just for DRV8462.
What is the difference between the DRV8452 and DRV8462?
Would it be ok to evaluate the…
Part Number: DRV8452 Tool/software: Hi,
I am evaluating the DRV8452 using SPI.
There is no problem with normal operation.
When I stop STEP Pulse , the "excitation pattern returns?" phenomenon occurs.
Due to this problem, it is not possible to return…
Part Number: DRV8452 Other Parts Discussed in Thread: DRV8462EVM Tool/software: Hi..
I have a new board with 3 DRV8452 connected via SPI. "Smaller motors" are working fine but we have a NEMA24 which should run with 300rpm. But it is getting noisy at…
Part Number: DRV8452 Tool/software: Hi TI Team,
I am started working on the DRV8452DDWR driver IC is rotate the stepper motor for my application.
I am having the own custom board and DRV8452DDWR driver IC populated on the custom board along with…
