PWM question with pic16f876
PostPosted: Tue Aug 24, 2004 10:57 am     Reply with quote
I want to drive a GM solenoid, part# 1997152 using a PWM signal. I assume that the PWM will have a limited current that it can drive. I checked the datasheet, http://ww1.microchip.com/downloads/en/DeviceDoc/30292c.pdf, but I dont see that information. How can I tell if this exceeds the solenoid? If it does exceed, what are some possible solutions? I figure that a relay would not be fast enought to keep up with a PWM signal.

Thanks,

Nick

This also looks interesting.
