DESCRIPTION
1
The UTC
USS40
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.
SIP-3
FEATURES
* Wide Temperature Operation Range of -40°С~+125°С
* Alternating Magnetic Field Operation
* Built-in Protection Diode
* Withstand Voltage 50V
* TTL and MOS IC are Directly Drivable by the Output
* The life is Semi Permanent because it Employs Contact-Less Parts
