DESCRIPTION
SIP-3
The UTC
SK1816M
is a semiconductor integrated circuit
utilizing the Hall effect. It designed 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, such as Speed sensor, Position
sensor, Rotation sensor, Contact-less sensor, and Motor control.
FEATURES
* Wide Temperature Operation Range of -30°С ~+125°С
* Alternating Magnetic Field Operation
* Built-in Protection Diode
* TTL and MOS IC are Directly Drivable by the Output
* The life is Semi Permanent because it Employs Contact-Less Parts
* SIP-3 and SOT-23 Package are Available.
