TB62209F Preliminary TOSHIBA BiCD Processor IC Silicon Monolithic TB62209F Stepping Motor Driver IC Using PWM Chopper Type The TB62209F is a stepping motor driver driven by chopper micro-step pseudo sine wave.

The TB62209F integrates a decoder for CLK input in micro steps as a system to facilitate driving a two-phase stepping motor using micro-step pseudo sine waves.

Micro-step pseudo sine waves are optimal for driving stepping motors with low-torque ripples and at low oscillation.

Thus, the
