Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 Hi
We made a version in September and found it OK, and then we made another version in October, with the same schematic diagram and the PCB of the motor It is the same, found that the motor…
Part Number: DRV8434A Hi Team,
1) M0 and M1 have Hi-Z inputs. Can this Pin float be interpreted as representing Hi-Z state? How to set up GPIOs if using monotholic GPIOs for control? Just with an open-drain output?
2) Other motor drive ICs have 1/10,1…
Part Number: DRV8434A I'm trying to setup stall detection for a Sanyo Denki 103H7823-5740 stepper motor (seems to be discontinued, so we will probably have to use something else in production).
Probably irrelevant, but in my setup, i have a PLC controlling…
Part Number: DRV8434A Dear Specialists,
My customer is evaluating DRV8434A and has a question.
I would be grateful if you could advise.

When we conducted a short circuit test between the AOUT1 output of the stepping motor driver DRV8434APWPR and GND…
Part Number: DRV8434A The stepper driver DRV8434A should be operated in "stall threshold" mode, i.e. STL_MODE = 1, STL_TH = input. For maximum flexibility , I would like to have the threshold voltage generated by the FPGA via a PWM - for this…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8452 , DRV8462 Hello,
sorry, if I have overseen the thread, where this might have been already covered. Please point me to it!
Is there any stepper motor driver, which detects at standstill, that…
Part Number: DRV8434A Hello,
We are using DRV8434A stepper motor driver for our application. For stall monitoring, we are using the driver in Torque count mode. Our external MCU is monitoring the analog voltage at TRQ_CNT/STL_TH pin for stall detection. We…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 We are seeing the same behavior described in this topic where the DRV8434A does not seem to automatically recover after a thermal shutdown (OTSD) or overcurrent condition (OCP) like the datasheet…

Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 , Hi,
I am currently working with the DRV8434AEVM as well as a custom PCBA with the DRV8434 stepper motor driver. I've found that with my current design as well as the evaluation board I am…
