DN8799MS

3 V operation Hall IC

s Overview

The DN8799MS is a 3 V operation Hall IC which

includes a Hall element, amplifier circuit, Schmidt circuit,

stabilized power supply and temperature compensation

circuit which are integrated on a single chip with a fine

patterning technology. The magnetic input signal is out-

putted by being converted to high or low. We have im-

proved the conventional circuit to realize a stable opera-

tion covering from low to high supply voltage and from

low to high temperature.

s Features

• Wide operating supply voltage range

• Wide operating ambient temperature (−40°C to +85°C)

• Package: Mini type (3-pin type)

(1.1 mm thick: Same as a standard transistor)

s Applications

• Cellular phone (detection of cover open/close), position sensor
