EDE1200 Unipolar Stepper Motor IC
 |
|
The EDE1200 Unipolar Stepper Motor IC is a 5 volt, 18 pin device designed to interface a logic-level input byte to a stepper motor. The EDE1200 is capable of automatically controlling a stepper motor in 'RUN' mode and of external pulsing in 'STEP' mode. Directional control is available, as well as both full and half-stepping for increased control resolution. The TTL/ CMOS level outputs sequence the stepper drive components, which consist of either four power transistors or a transistor array IC. Both setups are illustrated in our datasheet, and we offer component parts kits for these two arrangements as well.

As mentioned previously, the EDE1200 generates low-level timing signals that need to be amplified for the motor. We offer two power-semiconductor kits for use with the EDE1200. The first, the 'Power IC' Kit, is for use with most small to medium-sized motors. The second , the 'Power Transistor' Kit, is for larger stepper motors. Hookup schematics for both arrangements can be found in the EDE1200 Datasheet. A ULN2003A or MJE3055T datasheet is included with the component kits.
