Description

The US66 is a one-chip solution for driving twocoil brushless DC fan and motors. It is especially suitable for relatively high-current rated operation as it can drive up to 600mA continuous output current.
 
The use of Melexis Soft Switching concept lowers the acoustic and electrical motor noise and provides smoother ration. This efficient solution of US66 is combined with an innovative slope control design controllable via a dedicated pin.
 
The US66 includes reverse voltage protection, locked rotor protection and thermal protection. Therefore, the IC stness perfectly suits for consumer and automotive-on-board applications.
 
Tachometer (FG) or Alarm (RD) open-drain output of US66 is available. It makes the connectivity with external interface such as hardware monitoring or Super I/O IC easier.
 
The US66 is delivered in RoHS compliant DC package (SMD) for automatic soldering
