Order Information:

Part number

US1881

Operate temperature

K: -40~125°C

Package

TO-92UA/SOT23

 

General Description: 
 
The US1881 is a bipolar Hall effect sensor IC fabricated from mixed signal CMOS technology. It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points. There are many applications for this HED in addition to those listed above. The design, specifications and performance have been optimized for commutation applications in 5V and 12V brushless DC motors. 
 
The output transistor will be latched on (BOP) in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package. Similarly, the output will be latched off (BRP) in the presence of a North field. The SOT-23 device is reversed from the UA package. 
 
The SOT-23 output transistor will be latched on in the presence of a sufficiently strong North pole magnetic field applied to the marked face. 
 

 

Applications: 
 
-Solid state switch.
