LINEAR INTEGRATED CIRCUIT
COMPLEMENTARY OUTPUTS
HALL EFFECT LATCH IC
DESCRIPTION
The UTC UH276 is a Latch-Type Hall Effect sensor with built-in
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 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
* 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
switching.
* Build-in reverse protection diode.
