DN8899UAS
Hall IC for alternative magnetic field (SOH-4D type)
s Overview
The DN8899UAS is a Hall IC in which a Hall element,
an amplifier circuit, Schmidt circuit, stabilized power sup-
ply and temperature compensation circuit are integrated
onto a single chip using IC technology. It amplifies Hall
element output in the amplifier and converts it into a digital
signal through the Schmidt circuit so as to drive the TTL
or MOS IC directly.
The characterisitcs are guaranteed at a normal tem-
perature (25°C) and a high temparature (135°C).

The characterisitcs are tested and guaranteed at a nor-
mal temperature (25°C) and a high temparature (135°C)
3.0±0.3
5.4±0.4
for all devices.
High sensitivity and low drift
ESOP004-P-0200
Stable temperature characteristics due to the built-in tem-
perature compensation circuit
Wide operating supply voltage range (VCC = 4.5 V to 16 V)
Operating in alternative magnetic field
Direct drivability of TTL and MOS ICs with output
Open collector output
The hysteresis width of the zero-cross type includes "0" tesla point.
Operation magnetic flux density does not depend on the supply voltage due to the built-in stabilization power supply.
Surface mount package
s Applications
Speed sensor, position sensor, rotation sensor, key board switch and micro switch etc.

Note) 1. Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25°C.
2. The reverse insertion of this IC will cause its breakdown.
3. It will operate normally in several tens of ms after power on.
4. 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.
5. 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.
6. *: Shows the allowable power consumption at Ta = 135°C.
If the operation condition exceeds 60 mW, take measure in mounting and etc.
