I had looked at datasheet and it shows notch but I’ve been fooled before by them.
No commitment taken to design or produce NRND: How much current does your motor require? There is no way for us to help you without that. Take a photo of your circuit close uln2004an datasheet from directly above about 1 foot so we can see the wiring.
Contacts Learning Longevity Commitment. Uln2004an datasheet, I uln2004an datasheet a six wire unipolar stepper motor uln2004an datasheet I was trying to use with the stepper motor knob example on this site. I Agree Read More. I realized that I had a 1. But I’ve wired up all as shown so I can’t see whats wrong.
Then there’s the unipolar schematic listed that you unl2004an to expand. Draw a schematic and take a photo of it and post it.
Smart Home and City Smart Industry. Product is in volume production. No availability reported, please contact our Sales office. Product is in design feasibility stage.

Molex on Sep 01, Sustainability Priorities Sustainability Reports. Communications Equipment, Computers and Peripherals. Or one of those uln2004an datasheet kits. Take uln2004an datasheet photo of the schematic and post it.
I believe I had one other type of IC where uln2004an datasheet circle designated where pin 1 was instead of notch. Measure the winding resistance with a meter.
Robin2 Brattain Member Posts: Does any know from this chip? Product is in design stage Target: Not Recommended for New Design. Don’t try to uln2004an datasheet the circuit again until you hear from us.
SGS Thomson Microelectronics
Resources Technical Documentation Product Specifications. However I get magic smoke with the IC soon as hook up power.
Uln2004an datasheet Simulators and Models. Product is under characterization. Two or three hours spent thinking and reading documentation solves most programming problems.
Each channel is rated at mA and can withstand peak currents of mA. The smoke escaped because too much current was taken through the chip. Voltage will work datashdet power supply VDC uln2004an datasheet. If you can’t read the number on the IC and match uln2004an datasheet and the IC shape to the illustration on the datasheet then there is something wrong. Please contact our sales support for information on specific devices.
Make sure you label all the pins with the pin function labels shown on the drawing of the ic datssheet the datasheet. I’ll see if they guy knows the amps uln2004an datasheet. General terms and conditions. These versatile devices are useful uln2004an datasheet driving a wide range of loads including solenoids, relay DC motors, LED display filament lamps, thermal printheads and high-power buffers. Though I was just looking to do the getting them to move uln2004an datasheet with the darlington’s I had.
Don’t power up the circuit any more if you got smoke because that means uln2004an datasheet chip is already fried.
