The US661 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 Alarm (RD) output is a safety signal which allow to detect if the fan rotates or not. Since it is an open-drain output, it makes the connectivity with external interface easier.
The device is delivered in RoHS compliant DC package (narrow SOIC8) for automatic soldering.
