I guess I’m not understanding how this thing is supposed to work. In this configuration, I get. Tom Sisk Sisk Consulting Inc.
National Semiconductor – datasheet pdf
They are not meant to imply that the devices. I’m tired and frustrated for today. The V I ON voltage limit guarantees a minimum output sink current per the specified test conditions. I also tried connecting the positive terminal of the external 24vdc power supply to the DS common eatasheet instead of VDD.
Can I not get there with a 5v input? Europe Customer Support Center. When I switch the power on I get.
National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the ds20003 at any time without notice to change said circuitry and specifications.
Or, does the input pin serve as both an enable and supply voltage? You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.
Stock Quick Quote. Well, what if you were able to see a piece of equipment before you purchased it? I’ve tried every approach suggested here and then some, still the biggest or smallest output I could get was Peak Collector Current vs. This does not seem to be the case.
All limits apply to the complete Darlington series except as specified for a single device type.
They should normally be reversed biased and serve to protect the drivers from the reverse polarity pulse when the magnetic field around the solenoid coils collapses when the driver is turned off.

In that configuration I get -3vdc on the ouput when VDD is switched on. It’s like having the store come to you! Click a thumbnail to view larger image: So far I’ve had no luck, even following the schematic at the link you posted.
Here is the connection diagram from the data sheet: Is the common pin supposed to be the supply voltage for the output pin? All units feature com. Sign In or Register to comment.

Package Thermal Dissipation Ratings. The problem turned out to be two-fold. Here is what I have right now: Chris Savage Parallax Engineering Posts: You guys are great! I’ll admit I don’t have much experiance dealing directly with transisters, but I thought I could handle this apparently simple device.
