1 Functional Diagram  
2 General Description  
The US890/891 is a one-chip solution for driving  
two-coil brushless DC motors and fans.  
Based on the advanced Melexis CMOS process,  
the IC contains a Hall-effect sensor, dynamic  
offset correction and powerful output drivers with  
1200mA peak output current capability.  
Specially designed for driving large fans, the  
device is optimized for low start-up voltage.  
Frequency Generator or Rotation Detection is  
available. The open-drain output makes easier the  
connectivity with any external interface such as  
hardware monitoring or Super I/O IC.  
These features are combined with the Melexis  
patented no-VDD design to fit the IC in a small 4-  
pin VK package.
