The Toshiba TB62200AF is a monolithic Bi-CMOS integrated circuit designed to drive two pairs of two-phase stepping motors. It utilizes a chopper micro-step pseudo sine wave control method to achieve high efficiency and low torque ripple. The IC features built-in 16-bit latch and shift registers for each motor pair, along with 4-bit D/A converters for precise micro-stepping control.
