Single-Stepping Motor Driver IC with Dual DC/DC Converter Driven by Chopper Micro-Step Pseudo Sine Wave
The TB62205FG is a single-stepping motor driver with dual DCDC converter driven by chopper micro-step 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 TB62205FG is suitable for driving stepping motors at high efficiency and with low-torque ripple, and supports Selectable Mixed Decay Mode for switching the attenuation ratio at chopping. Also, the IC incorporates two DCDC converters, enabling two individually configurable power supplies.
