TB62209FG
Stepping Motor Driver IC Using PWM Chopper Type TB62209FG The TB62209FG is a stepping motor driver driven by chopper micro-step pseudo sine wave. The TB62209FG 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 TB62209FG can easily drive stepping motors with low-torque ripples and at high efficiency. Also, TB62209FG consists of output steps by DMOS (Power MOS FET), and that makes it possible to control the output Weight: 0.79 g (typ.) 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.
