TOSHIBA TB62207BF TB62207BFG TOSHIBA BiCD Process Integrated Circuit - Silicon Monolithic TB62207BF TB62207BFG Stepping Motor Driver/DC Motor Driver Select, DC-DC Converter and Reset Driven by Chopper Microstep Pseudo Sine Wave The TB62207BF/BFG is a dual stepping motor driver./DC motor driver switching enabled, DC-DC converter and reset driven by chopper microstep pseudo sine wave. To drive a two-phase bipolar-type stepping motor, a 16-bit latch and a 16-bit shift register are built in the IC. The IC is suitable for driving stepping motors with low-torque ripple in a highly efficient manner. In addition, a signal axis can be switched to serve as a PWM driver for two DC motors. By equipping the stepping motor driver with Selectable Mixed Decay Mode for switching the attenuation ratio during chopping and also equipping it with a DC/DC converter, it is possible for the IC to supply external voltage.
