Hey Everyone!
I have my first teensy on the way (3.2) and I was hoping to get a little bit of advice.
I am planning to use the Teensy to control two 12V Hydraulic solenoids. Bottom of page 35 in manual for PVEH.

I have a regulated 12V source available.
The solenoids are at 0 at 0.5 * SupplyV
A-port ↔ B-port 0.25 → 75 * SupplyV
My thoughts were:
PWM outputs set to 187500Hz
Two logic level N MOSFETs on two Teensy pins
RC filter after each MOSFET with R=1K and C=100nF
This will give me a settling time of 0.00023 seconds and a ripple of 0.159v (~1%).
Does this sound like a good approach?
Thanks,
Sam
