Part Number: DRV8834 Other Parts Discussed in Thread: DRV8880 I am attempting to drive a small stepper motor with the DRV8834. This motor has a 48 Ohm winding resistance and is intended to be operated at 4V. The peak current should be less than 100mA…
Part Number: DRV8834 Hi,
This is regarding DRV8834 step selection Mode.
We were using M1=1 & M0=1 mode(1/16 micro-step mode) .Due to application requirement ,shifted to M1=1 & M0=Z mode(1/32 micro-step mode)
At step frequency 1KHz, Motor works as…
Other Parts Discussed in Thread: DRV8834 Hi,
our customer use DRV8834 in stepper motor application. Some devices cause buzzer noise on the motor.
The problem could be fixed by dedicated device. Failure could be reproduced.

Part Number: DRV8834 Hi Team,
We understand that the behavior of OCP and H bridges is the following chart.
Is my understanding correct?
And, our customer would like to know the actual waveform at over current protection(OCP).
Could you please…
Other Parts Discussed in Thread: DRV8834 Hi,
My customer has a question about decay setting at GUI of EVM. Situation is at tab of "internal microsttepper control". Please see the following picture of black circle.
Could you let me know about Decay…
