DN8899 Datasheet, PDF (1/3 Pages) Panasonic Semiconductor – Hall IC (Operating Temperature Range Topr=-40 to +100°C, Operating in Alternative Magnetic Field)

DN8899/SE/TE/S
Hall IC (Operating Temperature Range
Topr=–40 to+ 100˚C,
Operating in Alternative Magnetic Field)
s Overview
The DN8899/SE/TE/S is a combination of a Hall element,
amplifier, Schmidt circuit, and stabilized power supply/temper-
ature compensator integrated on an identical chip by using the
IC technology. It amplifies Hall element output at the amplifi-
er, converts into a digital signal through the Schmidt circuit,
and drives the TTL or MOS IC directly.
s Features
• High sensitivity and low drift
• Stable temperature characteristics due to the additional tem-
perature compensator
• Wide operating supply voltage range(V_CC=4.5 to 16V)
• Operating in alternative magnetic field
• TTL and MOS ICs directly drivable by output
• Semipermanent service life due to no contact parts
• Small change of the operating flux density against mechani-
cal stress
• Output open collector
• “0” gauss point in the zero cross type hysteresis width
s Applications
• Speed sensors
• Position sensors
• Rotation sensors
• Keyboard switches
• Microswitches
Note) This IC is not suitable for the car electric equipment.
