Part Number:DRV110
I am designing a circuit to drive a small solenoid at a very high frequency: ideally >100Hz. The solenoid I am evaluating is a Ledex 195201-234: 50% duty, 8.8V/13.1Ohm= 672mA. I only need to drive it a small fraction of the possible stroke (about 0.5mm, that's roughly 20% of possible stroke). There is a return spring.
Is the DRV110 the right driver for this application? I like the idea of being able to use different voltages, and the solenoid manufacturer recommended a constant current drive to get high speeds. I need a sawtooth waveform of stroke/time, so should I just set the keep time to zero? The solenoid manufacturer also suggests a coil suppression circuit (below).
Obviously for PWM I will need a fast recovery diode. Does the rest of the coil suppression circuit make sense, used with the DRV110? They recommended a ceramic 0.1uF cap.
Thanks!
