BIPOLAR LATCH TYPE
HALL - EFFECT FOR
HIGH-TEMPERATURE
OPERATION
„
DESCRIPTION
SK1812 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, contactless switches, and the
like.
„
FEATURES
* Wide supply voltage range of 2.5V to 20V
* Wide temperature operation range of -20℃~+125℃
* Alternating magnetic field operation
* TTL and MOS IC are directly drivable by the output
* The life is semipermanent because it employs contactless parts
* SIP-3 and SOT-23 package
„
*Pb-free plating product number: SK1812L
APPLICATIONS
* Speed sensor
* Position sensor
* Rotation sensor
* Contact-less sensor
* Motor control
