BD6726FU is a single-phase full-wave motor driver that can be controlled by DC/PWM input, using PWM soft switching drive, and built-in speed feedback control circuit
The BD6726FU is a single‑phase full‑wave motor driver IC designed for fan motors. It includes a pre‑driver compatible with external transistors, speed control via DC/PWM input, PWM soft‑switching drive, and a built‑in speed‑control circuit using rotation‑speed feedback.
Key specifications include a supply voltage rating up to 20 V, power dissipation of 874.7 mW, operating temperature range from –40 °C to +100 °C, and defined high‑side and low‑side output voltages and currents. The document also outlines cautions such as absolute‑maximum ratings, reverse‑polarity protection, thermal shutdown behavior, and recommended grounding and capacitor practices.
