1 Functional Diagram

2 General Description

The US651/661 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 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.

Tachometer (FG) or Alarm (RD) open-drain output

is available. It 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 (SMD) for automatic soldering
