TB62212FTAG is a dual bidirectional step motor driver, which can drive up to 4 brushless DC motors, or combine to drive a single step motor. Its features include low RON, single power supply, internal VCC voltage regulator, over temperature detection circuit, over current detection circuit, power on reset circuit etc.
The TB62212FTAG is a PWM‑chopper dual stepping motor driver capable of driving up to four brushed DC motors or two stepping motors. It integrates bipolar stepping motor control, internal VCC regulator, and protection circuits such as over‑temperature (TSD) and over‑current (ISD) detection.
The document provides block diagrams, pin configurations, motor drive modes, electrical specifications, and usage notes for safe design and implementation of the driver in industrial and consumer applications. This manual is written in Japanese.
| On‑Resistance (normal mode) | 2.2 Ω |
|---|---|
