DESCRIPTION
SIP-3
U18 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 2.5V to 20V
* Wide temperature operation range of -20℃~+125℃
* Alternating magnetic field operation
*Pb-free plating product number: U18L
* TTL and MOS IC are directly drivable by the output
* The life is semipermanent because it employs contact less parts
* SIP-3 package
ꢀ
APPLICATION
* Speed sensor
* Position sensor
* Rotation sensor
* Contact-less sensor
* Motor control
* Built-in protection diode

Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The device is guaranteed to meet performance specification within 0℃~+70℃ operating temperature range
and assured by design from -20℃~+125℃.

Note 1.BOP = operate point (output turns ON ); BRP = release point ( output turns OFF); BHYS = hysteresis
(BOP –BRP).As used here, negative flux densities are defined as less than zero (algebraic convention).
Typical values are at Ta = +25℃ and VCC = 12V.
