DN8799MS

3 V operation Hall IC

■ 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 out­putted by being converted to high or low. We have im­proved the conventional circuit to realize a stable opera­tion covering from low to high supply voltage and from
low to high temperature.

■ Features

• Wide operating supply voltage range

(V

= 2.7 V to 14.4 V)

CC

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

• Package: Mini type (3-pin type)

(1.1 mm thick: Same as a standard transistor)

■ Applications

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

Note) 1. Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.

2. The reverse insertion of this IC will cause its breakdown.

3. It will operate normally in several tens of ms after power on.

4. This IC is designed for a general use and if you want to use for an automotive use, please consult our staff of the nearby
sales office beforehand.

Note) 1. Symbol BH-L stands for the operating magnetic flux density where its output level varies from high to low.

2. Symbol BL-H stands for the operating magnetic flux density where its output level varies from low to high.

3. The variation of operating magnetic flux density does not depend on supply voltage due to its built-in stabilized power
source. (VCC should be confined to the range of 2.7 V to 14.4 V.)

4. A supply current changes by maximum 1 mA when its output level varies from high to low.
