1 Functional Diagram  
2 General Description  
The US90A/91A is a one-chip solution for driving  
two-coil brushless DC cooling fans.  
Based on the advanced Melexis CMOS process,  
the IC contains a Hall-effect sensor, dynamic  
offset correction and low side output drivers.  
Frequency Generator or Rotation Detection is  
available. The open-drain output makes the  
connectivity with any external interface such as  
hardware monitoring or Super I/O IC easier.  
These features are combined with the Melexis  
patented no-VDD design to fit the IC in small 4-pin  
VK and VA package.  
The device is also delivered in DC package for  
automatic assembly.
