s Overview
The DN6852 is an integrated circuit making use of Hall
effects. It is designed particularly for operating at a low supply
voltage in one way magnetic field. It is suitable for various sen-
sors and contactless switches.
s Features
Wide range of supply voltage : 3.6 to 16V
Operating in one way magnetic field.
TTL and MOS ICs directly drivable by output
Semipermanent service life because of no contact parts
Drivable with a small magnet
3-pin SIL plastic package (3-SIP)
Open colector
s Applications
Speed sensors
Position sensors
Rotation sensors
Keyboard switches
Microswitches
Note) This IC is not suitable for car electrical equipments.

s Precaution on Use
1. Change of the operation magnetic flux density dose not depend on the supply voltage,
because the stabilization power supply is built-in.
(only for the range ; V
CC
=4.5 to 16V)
2. Change from "H" to "L" level increases the supply current by approx. 1mA.
