DESCRIPTION
The UTC UH211 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, UH211 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

MULTIPLEXED TWO-WIRE HALL-EFFECT SENSOR ICs

The UGN3055U HALL-EFFECT SENSOR is a digital magnetic sensing IC capable of communicating over a two-wire power/signal bus. Using a sequential addressing scheme, the device responds to a signal on the bus and returns the diagnostic status of the IC, as well as the status of each monitored external magnetic field. As many as 30 SENSORs can function on the same two-wire bus. This IC is ideal for multiple SENSOR applications where minimizing the wiring harness size is desirable or essential.

FEATURES
■ Complete Multiplexed HALL-EFFECT IC with Simple Sequential Addressing Protocol
■ Allows Power and Communication Over a Two-Wire Bus (Supply/Signal and Ground)
■ Up to 30 HALL-EFFECT SENSORs Can Share a Bus
■ SENSOR Diagnostic Capabilities
■ Magnetic-Field or Switch-Status Sensing
■ Low Power of BiMOS Technology Favors Battery-Powered and Mobile Applications
■ Ideal for Automotive, Consumer, and Industrial Applications
