EPSON Stylus Color Cr Motor Driver Circuits

The CR motor driver IC SLA7043M IC15 sends motor phase data using the serial data XCRCLK, XCRSTB, CRASERI, CRBSERI and voltage reference data CRV from the gate array E05B34 to the driver to control the phase current in the driver. The data output from the phase A and phase B CRASERI, CRBSERI are transferred synchronizing with the clock signal XCRCLK . Then the data is read at the driver IC by the strobe signal XCRSTB . This sequence enables the micro step with a minimum of 0.026 mm pulse driven...
