DATA CONVERTER
The PG001M CMOS IC converts parallel-data signals from a low-
cost, 8-bit microprocessor or microcontroller into a serial-data format
compatible with the SLA7042M and SLA7044M power multi-chip
modules to drive unipolar PWM, high-current stepper motors. The
converter provides for five basic modes of operation:
1) normal, two-phase, full step (100% torque vector),
2) two-phase 'boosted' torque (141% torque vector),
3) half-step, constant torque operation (using a 2-1-2 output switching),
4) quarter-stepping utilizing ratioed currents for constant torque, and
5) microstepping (1/8th steps) for quiet, smooth, resonance-free motor
performance.
The PG001M is supplied in a low-cost 16-pin dual in-line plastic
package. It is rated for continuous operation over the temperature
range of -20°C to +85°C.
