UH277
DESCRIPTION
The UTC UH277 is a Latch-Type Hall Effect sensor with built-in plementary output drivers. It’s designed with internal temperature pensation 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.
- FEATURES
- Widen Power Supply range from 3V ~ 20V.
- On-chip Hall sensor with excellent hysteresis.
- Open Collector outputs had the sinking capability up to 300m A.
- Output Clamping Diodes reduce the peak output voltages during switching.
- Build-in reverse protection diode.
