Panasonic DN6852 Datasheet

■ 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 sen­sors and contactless switches.

■ 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

■ Applications

•

Speed sensors

•

Position sensors

•

Rotation sensors

•

Keyboard switches

•

Microswitches

Note) This IC is not suitable for car electrical equipments.

■ Flux-Voltage Conversion Characteristics

■ 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 ; VCC=4.5 to 16V)

2. Change from “H” to “L” level increases the supply current by approx. 1mA.
