Lsi LS7290 stepper motor controller driver DIP24
Stepper Motor Controller . (24 Pins) LS7290
Datasheet: http:// /pdfs/Data_Sheets/LS7290.pdf
Controls two-phase Bipolar and four-phase Unipolar motors
Inexpensive replacement for L297.
Direct interface to L298 for Bipolar motors
Interface to four AND Gates driving four N-Channel MOSFET's for Unipolar motors
Programmable step sizes: Full and 1/2, *1/4, *1/8, *1/16, *1/32
Maximum stepping rate: greater then 30k per second.
Programmable inter-step blanking delays: 1.25us, 2.5us, 3.75us and 5us at 8Mhz.
H-bridge PWM resolution: 0.39%
Two PWM and Four Phase outputs for H-Bridge control.
On-chip Crystal Oscillator, RC Oscillator or External source, controls Step Frequency and Duty Cycle.
I can also provide by request a working schematic of Stepper Motor Driver 80V 7A. Feel free to ask if you have any questions about this chip.
This is a final sale, sorry, no returns.
There are total of 15 LS7290 on sale. The price is 3.75USD for 1 controller.
For an extra 1.50$USD I can add 24 pin socket for this chip.
This cost includes cost of packaging materials and antistatic bag.
