Hi,
I am working on an electromechanical solenoid actuator with 400 mohm load and i need max 2 amps. I use DRV8835 and DRV8838 and apply 3 volts for driver side and 2 volts for motor side with PWM signals (20kHz) obtained from dSPACE 1103 for adjusting the voltage amplitute. I have one output for system (aout1 amd aout2) and i use AENB for PWM signals. When i try to run, system doesnt work. I guess the problem is with low resistance load. On the other hand, i tried with a 330 ohm load, both driver worked perfect.
It will be great if somebody give some feedback. Thanks,
