The UTC H1277 is a semiconducting integrated Hall Effect Sensor IC.
It is just like all the hall sensitive Hall Effect Sensors designed to
work in the situations which the accurate track is extremely small and
the changes in magnetic flux density-changes are generally too small to
Besides those features shared in all Hall Effect Sensors, H1277 can apply to various kinds of applications, such as contact-less switches, motion detectors, gear tooth sensors, proximity detectors, and electric communication of DC brushless motors, etc.
* Hall Sensor On-Chip
* Output Zener Diodes to Clamp the Peak Output Voltage
* Frequency Generation Output
* High Output Sinking Capability (nearly to 400mA)
* High Sensitivity Hall Effect Sensor IC: ±65G
