DN6849UBS
Hall IC for alternative magnetic field
■ Overview
The DN6849UBS is a Hall IC in which a Hall element,
an amplifier circuit, Schmidt circuit, stabilized power supply and temperature compensation circuit are integrated
onto a single chip using IC technology. It amplifies Hall
element output in the amplifier, converts it into a digital
signal through the Schmidt circuit so as to drive the TTL
or MOS IC directly.
■ Features
• High sensitivity and low drift
• Stable temperature characteristics due to the built-in tem-
perature compensation circuit
• Wide operating supply voltage range
(V
= 4.5 V to 16 V)
CC
• Operating in alternative magnetic field
• Open collector output
■ Applications
• Speed sensor, position sensor, rotation sensor and key board switch

Note) 1. The reverse insertion of this IC will cause its breakdown.
2. It will operate normally in several tens of ms after power on.
3. Use it within 100 mT of magnetic flux density, because if 100 mT or more is applied, the output of Hall IC is likely to be
inverted.
4. Since this IC requires a special assembly, its anti-moisture characteristic is poor compared with other ordinary ICs.
If high reliability is required, you should dry PCB well after mounting and mold them with resin over the PCB.
5.*1: Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
2: Shows the allowable power consumption at Ta = 100°C.
