Part Number: DRV8880 Other Parts Discussed in Thread: DRV8711 Hi,
I want to use the AutoTune feature of DRV8880 with a stepper motor with 5 A current(RMS). Is it possible to use external MOSFETs driver with DRV8880 for use with higher stepper motor currents…
Other Parts Discussed in Thread: DRV8880 , DRV8880EVM Dear Motor Driver support team,
I control the driver on the DRV8880 Evaluation Module Board from the DSP on the C2000 Piccolo LaunchPad Evalution Kit Board.
The microstepping setting can be set by the…

Hi,
My customer is using DRV8880. He changes the step with M1/M0 setting during motor operation. He wants to know the behavior indexer operation.
For example.
Maybe, when customer changes from 1/4 step to 1/16 step, step is changed…
Other Parts Discussed in Thread: DRV8880 Hi Motor driver support team,
I operate a stepper motor by DRV8880.
However suddenly the motor stopped.
I observed signals with/without stepper motor after that.

TRQ is the percentage value in the datasheet.
Is TRQ ratio value ?
plz help me.
Other Parts Discussed in Thread: DRV8880 , TIDA-00830 Dear Motor Driver support team,
I operate two-phase stepping motor by the driver of DRV8880 with the supply voltage of 24V and 2A full scale current at full step mode.
I changed DIR signal at every…
Dear Motor support team,
I set the IFS to be 2.0A maximum peak current with 3.3V Vref, 250*10^-3ohm Rsens and 100% TRQ setting.
I confirmed IFS setting with P.18 in www.ti.com/.../drv8880.pdf.
However I observed about 1.4A peak current at 800pps and 1…
