Description

The US661 is a one-chip solution for driving
two-coil brushless DC fan and motors. It is
especially suitable for relatively high-current rated
operation as US661 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 ration. This efficient solution of US661 is combined with an innovative slope control design controllable via a dedicated pin.
 
The US661 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 US661 is available. It makes the connectivity with external interface such as hardware monitoring or Super I/O IC easier.
 
The US661 is delivered in RoHS compliant DC package (SMD) for automatic soldering
