Two-Coil Fan Driver - Low Noise (Tachometer Output)

The US651 is a one-chip solution for driving two-coil brushless DC fan and motors. It is suitable for typical applications as it CAN drive up to 350mA continuous output current.The use of Melexis Soft Switching concept lowers the acoustic and electrical motor noise and provides smoother operation. This efficient solution is combined with an innovative slope control design controllable via a dedicated pin.The device includes reverse voltage protection, locked rotor protection and thermal protection. Therefore, the IC robustness perfectly suits for consumer and automotive-on-board applications.The integrated Tachometer (FG) output follows the Hall Sensor signal which allows to determine the rotation speed. Its open-drain output makes the connectivity with external Interface such as hardware monitoring or Super I/O IC easier.The device is delivered in RoHS compliant DC package (narrow SOIC8) for Automatic soldering.
