SENSITIVE HALL-EFFECT SWITCHES FOR HIGH-TEMPERATURE OPERATION

DESCRIPTION

UTC U349 is a semiconductor integrated circuit utilizing the Hall

effect. It has been so designed as to operate in the alternating

magnetic field especially at low supply voltage and operation over

extended temperature ranges to +85°С.This Hall IC is suitable for

application to various kinds of sensors, contact-less switches, and

the like.

FEATURES

* Wide temperature operation range of -20°С ~ +85°С

* Wide supply voltage range of 4.5V to 24V

* TTL and MOS IC are directly drivable by the output

* Reverse Battery Protection

* Activate with Small, Commercially Available Permanent Magnets

* Solid-State Reliability

* Resistant to Physical Stress
