Sell Original new Only. We also be able order parts from other part of the world in very short time.

What I thought was pin 5 is actually pin 1, and it is indeed power. Dear Sir The information you have provided is really good. I pulled pin 4 low, and the tiny mirror spun up with a whine to about 13, RPM as measured by the tach output! You may describe your other requirements here.

ANSB Datasheet, PDF – Qdatasheet

Product Photos Show Photo shown is representation only. I have the same unit, but my interest was on the other side of the box. And make stepper move forward, and back, or just spin one direction, to be able to see a dot moving along the line. It was a logic low. Performance the engine test – the same result.

Most of the other pins disappear inside the undocumented chip. It also spins at lower voltage in as well. I was trying to power it up, but no success. How to Contact Us? On the motor board the pin 1 is closest to the right side of the board with the connector at the bottom. Digging through my junk box today, I unearthed the scanning mirror from a laser printer, otherwise known as the Heart of the LaserJet.

By rotating the mirror very slowly by hand, I counted 6 pulses per revolution. I suggest you throw it away. Mail will not be published.

an8247SB datasheet

Alibaba Assessed Gold Supplier. So pin 5 is a synchronization input. November 1, 3: I KNOW this part was working. First I tried connecting a 10K pullup resistor to pin 2 on the motor driver board to 3. I found your post here, I know it was long time ago, but have you got this circuit? This must be the tach output. I shall throw it out after a few months. Privacy Policy Terms of Use. dahasheet

What I suspect to be pin 5 appears to be the power supply since it connects to two very low valued resistors 0. Based on that I conclude that it is very likely a 12V rail. There must be a capacitor in series somewhere on datashdet motor board, and that means the pin is designed for AC signals. Connector Pin — Chip pin as follows: The motor will not spin up without the sync signal, and it seems happiest with something around Hz. Comment moderation is an82247sb and may delay your comment.

January 29, Or maybe know where I can find it? All the best, Tomasz Bajraszewski, Poland – Anonymous. I experience that my control pin is not frequency controlled but rather the duty cycle controlled qn8247sb motor speed. Can you help, where I can find the electronic circuit of this block and all printer?

Only the ANSB is the same. I not so well understand in English, only in Russian. By changing the frequency, I could manipulate the motor speed. Next I probed the voltage on the other two pins, which were both weakly pulled up to about 3. Normally ,it take days reach your hands. Pin 2 had a 10K pullup to some low voltage supply, pin 4 went straight into the microcontroller, and pin 5 came from an RC filter ddatasheet the microcontroller. I need am8247sb very much, please for any help.

April 22, 7: Order 1 Brand Name world ic stock Brief Description 1.

I connected ground to pin three, 12v to pin one and I connected pin 4 to ground to pull it low and the motor spun like a charm. Credit C ard 5. You’re our first Russian customer. Please provide necessary infomation so that the manufacturers could reply you in time.
