BD6722FS is a single-phase full-bridge motor driver produced by Toshiba, which features speed control, current limiting, PWM soft switching drive and so on.
The BD6722FS8S is a single‑phase full‑wave motor driver for fan motors. It offers speed control via DC/PWM input, a current‑limit circuit and PWM soft‑switching drive. The document provides absolute maximum ratings, operating conditions, electrical characteristics, package outlines, block diagram and terminal definitions.
Key specifications include a supply voltage up to 20 V, power dissipation of 812.5 mW, operating temperature range –40 °C to +100 °C, and high‑side/low‑side output voltages of 34 V. The handbook also lists important cautions such as avoiding reverse polarity, providing protection against back‑EMF, and ensuring proper thermal design.
