DESCRIPTION
The UTC SK1816 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℃.
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.

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℃.
