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
(V_CC = 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 kΩ)
■ Applications
• DC brushless motor, fan motor, rotation sensor, detec-
tion of cover open/close (example for a cellular phone),
position sensor
