DIGITAL HALL-EFFECT SENSOR ICs

DESCRIPTION

The UTC UH8108 sensor ICs (Integrated Circuits) is small,

versatile, digital Hall-effect devices operated by the magnetic field

from a permanent magnet or an electromagnet. This sensitive

device is designed to meet a wide range of potential applications

with low power requirements.

This low-power sensing device uses CMOS technology and a

timing circuit that turns the power on for only a short time - it is off

for the rest of the period (duty cycle) - significantly reducing the

average current consumption.

The UTC UH8108 responds to either a North or South pole,

meaning that it doesn’t require the magnet polarity to be identified,

providing an easier installation and potentially reducing system cost.

The product can operate from a supply voltage as low as 2.8V,

promoting energy efficiency.

FEATURES

* Omnipolar detection (polarity detection for both S and N features dual outputs)

* Push-pull output does not require external pull-up resistor
