TB62207BF/BFG is a step motor driver chip produced by Toshiba. It uses dual-channel step motor driver/DC motor driver switching + DC/DC converter + reset function, with the characteristics of low torque ripple and high efficiency.
The TB62207BF/BFG is a dual stepper‑motor driver that can also drive two DC motors. It uses a chopper‑type micro‑step drive with selectable mixed‑decay mode and includes an internal 1.5 V‑5 V adjustable DC/DC converter for external voltage supply. The device integrates 16‑bit shift registers and latches to control two bipolar stepper motors with high efficiency and low torque ripple.
The document provides a block diagram, pin‑out tables, logic unit description, current‑control circuits, and mechanical data such as package type (HSOP36) and dimensions. Soldering recommendations, protection features (over‑current, over‑temperature, reset), and handling notes are also included. This manual is written in Japanese.
