The PG001M CMOS IC converts parallel-data signals from a lowcost, 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 PG001M 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 to +85.
