HALL EFFECT LATCH IC
DESCRIPTION
The UTC UH277 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 UH277 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.
