DN8797MS
3 V operation Hall IC
One-way magnetic field operation
Overview
The DN8797MS is a 3 V operation Hall IC which
includes a Hall element, amplifier circuit, Schmidt circuit,
stabilized power supply and temperature compensation cir-
cuit which are integrated on a single chip with a fine pat-
terning technology. The magnetic input signal is output-
ted by being converted to high or low. We have improved
the conventional circuit to realize a stable operation cov-
ering from low to high supply voltage and from low to
high temperature.
Features
Wide operating supply voltage range
(VCC = 2.7 V to 14.4 V)
Wide operating ambient temperature (40°C to +85°C)
Package: Mini type (3-pin type)
(1.1 mm thick: Same as a standard transistor)
Eqipped with an output pull-up resistor (typical 56 k)
Applications
DC brushless motor, fan motor, rotation sensor, detec-
tion of cover open/close (example for a cellular phone),
position sensor

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.
