Stepping Motor Driver IC Using PWM Chopper Type
TB62209F
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 TB62209F can easily
drive stepping motors with low-torque ripples and at high
efficiency.
Also, TB62209F consists output steps by DMOS (Power MOS
FET), and that makes possible to control the output power

dissipation much lower than ordinary IC with bipolar transistor output.
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.
