Hi Folks,
I'm hoping to control a VPP655 with a 25kHz PWM signal generated from a 3.3v microcontroller (which is not 5v tolerant), so I would like to know if the pump uses an internal pull-up resistor to 5v before I release any magic smoke. If it doesn't utilise a pull-up, would it accept a 3.3v directly from a microcontroller and still provide the entire 0-100% range?
Many thanks for any advice you kind folks can offer with this.
All the best,
Dax
