TB62209F Datasheet Stepping Motor Driver Ic

Manufacturer: Toshiba

Overview: TB62209F Preliminary TOSHIBA BiCD Processor IC Silicon Monolithic TB62209F Stepping Motor Driver IC Using PWM Chopper Type 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 Weight: g (typ.) 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.
