Part Number: DRV8434A Tool/software: We have set the micro-stepping to 1/16 and adjusted the Vref to 1.2V. Then the stall detection has improved. We are able to achieve close to 85-90% stall detection. Thanks for the support.
Hi Pradeep,
Pradeep NG said: Regarding Vref calculation, IFS is the peak current right? The motor current shown is a rms current (0.67A).
Yes this is correct.
Typically in stepper motors the current specification is specified with full-step driving unless…
Part Number: DRV8434A-Q1 Other Parts Discussed in Thread: DRV8434 Tool/software: I have two questions for the experts. 1. Can the TRQ_CNT/STL_TH PIN of the DRV8434 be connected to the GPIO of the MCU without the need to connect to the GPIO of the MCU? …
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 , , DRV8434S Tool/software: I have 2 questions about utilizing the DRV8434 driver IC to control a stepper motor, the questions are as follows:
1. Using DRV8434 to drive a stepper motor, how…
Part Number: DRV8434A Tool/software: The jitter during power-on is acceptable. In the case of constant power, we want to do every time the motor stops, the next start time do not shake. In addition, after the motor stops, how to maintain the stopped state…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434SEVM , Tool/software: Hi,
I am planning to use the DRV8434APWPR motor drive for one of the application. I have got the DRV8434SEVM board as well for the testing purposes.
I have below couple of…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434S Hi team,
My customer has several questions when using DRV8434A.
1. One of the parameters used in calculating full-scale current is TRQ_DAC. I didn't find a definition in the datasheet,…
Part Number: DRV8434A Hello,
I am using DRV8434A for stepper motor driving.
My question is in which mode the driver drives the motor: L/R or Chopper?
Thanks in advance and BR

Part Number: DRV8434A Hi experts,
1. Without VCC and VM is not connected to the power supply, what will it happen if the voltages apply to the output pins(AOUT pins and BOUT pins)? For example, the user mistakenly turns the motor and applies Back-EMF…
Part Number: DRV8434A Hi Team,
Issue: the motor does not spin.
Power supply is 15.8 V which is good. Sleep and Enable is high. Fault, TRQ and STL_REP is low. M0 and M1 is high,
For the CPL and CPH pins, the normal board has a pulse waveform, while the…
