UH276

DESCRIPTION 

The UTC UH276 is a Latch-Type Hall Effect sensor with built-in 

complementary output drivers. It’s designed with internal temperature

compensation circuit and built-in protection diode prevent reverse 

power fault. The application is aimed for brush-less DC Fan 

The UH276 Outputs operate as the Hysteresis Characteristics. The 

Outputs alternately ON and OFF when either the magnetic flux 

density larger than threshold BOP or the magnetic flux density lower 

than BRP. 

FEATURES 

* Widen Power Supply range from 3V ~ 20V. 

* On-chip Hall sensor with excellent hysteresis. 

* Open Collector outputs had the sinking capability up to 400mA. 

* Output Clamping Diodes reduce the peak output voltages during 

switching. 

* Build-in reverse protection diode.
