... TOSHIBA Bi-CMOS Processor IC Silicon Monolithic TB62201AFG Dual-Stepping Motor Driver IC for OA Equipment Using PWM Chopper Type The TB62201AFG is a dual-stepping motor driver driven by chopper micro-step pseudo sine wave. To drive two-phase stepping motors, Two pairs of 16-bit latch and shift registers are built in the IC. The IC is optimal for driving stepping motors at high efficiency and with low-torque ripple ...
