When driving stepping motor with DRV8834 in indexer mode, is it supported to control Ifs with xVREF?
My customer wants to use it to actively control the trip current depending on motor's driving or stopping state.
However, as the reference voltage scaling by internal DAC is listed in table 4, but I'm not sure if it support what my customer wants to do.
Also, if TI has any other motor driver recommendation for the requirement below, please let me know.
Stepper motor requirement:
Inductor resistance : 40Ω +/- 10%
Step count: 64 micro step
Max speed : 1320pps (1-2 phase excitation)
Max input voltage : 5.5V
Rated voltage : 4.6V
Minimum voltage : 4.0V
