Part Number: DRV8434S Other Parts Discussed in Thread: DRV8411A , DRV8411 Hello team,
On the datasheet, fullscale current is set by TRQ_DAC.
My customer would like to know how is the full scale current is regulated by current sense block, opamp, Kv and…
Part Number: DRV8434S Hello team,
I want to decide the bulk capacitor value for this device, but there is no equation for required capacitance.
I have watched the video: Voltage margin and bulk capacitance and found an equation below.
I believe the I from…
Part Number: DRV8434 Other Parts Discussed in Thread: DRV8428E Hi team,
May I know if it is poissble to drive 2ch brushed DC motors by DRV8434 like DRV8428E does? It seems it is not possible from the datasheet.
Best regards,
Shunsuke Yamamoto
Part Number: DRV8434S I'm currently reading out the torque count value, but I used multiple bipolar stepping motors.
The count value varies depending on the motor. I understand that this is due to the resistance value of the winding wire on the data…
Part Number: DRV8434 I designed my driver based on the eval kit since I had tried my stepper motor with TI0 DRV8434 Eval kit and it was working just fine. Now when i monitor the Current sent to the motor by my driver board, i can only see a DC signal instead…
Part Number: DRV8434S Hi!
I have been running SPI on drv8434s for a while now without issues, but with a non-TI board as the Controller. We are now working on migrating the controller to TI, but have been unable insofar to get SPI to work as expected. …
Part Number: DRV8434 Hi team,
May I know the possible minimum value of t_OFF and possible maximum value of t_OFF when DRV8434 is in smart tune Ripple Control Decay Mode?
Best regards,

Part Number: DRV8452 Other Parts Discussed in Thread: DRV8434S
The DRV8452 (SPI version) and DRV8434S are pin-to-pin compatible with each other, with DRV8452 offering some newer features and performance improvements at a competitive price-point. Very…
Part Number: DRV8434S Other Parts Discussed in Thread: MSP430F2617 , Hello,
I'm embarking on a project with a basic stepper motor using your CCS IDE. I have a question about the DRV8434S stepper driver.
In the DRV8434S GUI, I can easily specify the…
Part Number: DRV8434S Motor Driver team,
The EVM for DRV8434S has 3.3nF caps on each output AOUT1, AOUT2, BOUT1, BOUT2. These are listed as DNP. Can you explain when you would recommend installing them and why they are DNP?
Our customer is considering…
