DescriptionThe 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.
The IC supports Mixed Decay mode for switching the attenuation ratio at chopping. The switching time for the attenuation ratio can be switched in four stages according to the load.
