complementary output drivers. 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 Outputs alternately ON and OFF when either the magnetic flux
density larger than threshold B

* Power Supply range from 3V ~ 20V.
* On-chip Hall sensor with hysteresis.
* Open Collector outputs had the sinking capability up to 300mA.
* Output Clamping Diodes reduce the peak output voltages during
* Build-in reverse protection diode.
