SK8552
LOW VOLTAGE OPERATION
HALL IC
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
SK8552 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
℃
.This Hall IC is suitable
for application to various kinds of sensors, contact-less switches,
and the like.
FEATURES
* Wide supply voltage range of 3V to 20V
* Wide temperature operation range of -20
℃
~+125
℃
* TTL and MOS IC are directly drivable by the output
* The life is semipermanent because it employs contactless parts
* Equipped with an output pull-up resistor ( typical 20kΩ)
APPLICATION
* Position sensor
* Contact-less sensor
* Detection of cover (open/close)
