Hi, on Duplo post printing machine one of bipolar stepper driver IC DUPLO 4X-8009 burned.
[attachimg=1]
For long time i try to find this IC or complete board DUPLO UNIT 98H-8013. No success :(
DUPLO 4X-8009 used for control 2A per phase stepper motor.
It has 4 inputs, 4otputs (two H bridges), power supply +24V, GND and two 0.2 OHM current chopper resistor.
Please help to find this IC, or any information about it control inputs, manuals ect.
P.S. Now i try to replace this IC by L297+L298 curent chopper with 4 (ABCD) phase input.
