HALL-EFFECT SWITCH FOR

HIGH-TEMPERATURE

OPERATION

DESCRIPTION

SK1901

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 +125°С.This Hall IC is suitable for

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

the like.

FEATURES

* Wide supply voltage range of 2.5V to 20V

* Wide temperature operation range of -20°С~+125°С

* TTL and MOS IC are directly drivable by the output

* The life is semipermanent because it employs contact-less parts
