HIGH SENSITIVITY HALL
EFFECT SENSOR IC WITH
FG OUTPUT
„ DESCRIPTION
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 be operated.
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.
„ FEATURES
* 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
