HALL-EFFECT SWITCH
FOR 2-WIRE APPLICATIONS
This Hall-effect switch is a monolithic integrated circuit designed to
operate continuously over extended temperatures to +85°C. The unipo-
lar switching characteristic makes this device ideal for use with a simple
bar or rod magnet. The A3163ELT and A3163EUA are identical except
for package.
Suffix 'UA' Pinning
(ultra-mini SIP)
Each device includes a voltage regulator for operation with supply
voltages of 3.5 to 24 volts, reverse-battery protection, quadratic Hall-
voltage generator for low offset, temperature compensation circuitry,
small-signal amplifier, Schmitt trigger, and a constant-current open-
collector output, wired internally for true 2-wire operation. Noise
radiation is limited by control of the output-current slew rate.
Two package styles provide a magnetically optimized package for
most applications. Suffix ‘LT’ is a miniature SOT89/TO-243AA transis-
tor package for surface-mount applications; suffix ‘UA’ is a three-lead
ultra-mini SIP for through-hole mounting; it is also available with lead
forming for surface-mount applications (suffix 'UA-TL').

FUNCTIONAL DESCRIPTION
ELEMENT LOCATIONS
(±0.005" [0.13 mm] die placement)
Operation. The output of these devices turns on when a
magnetic field (south pole) perpendicular to the Hall
element exceeds the operate point threshold (BOP). After
turn on, the output will source current (IOUT(H)) equal to
the device operating current plus a current source. When
the magnetic field is decreased (south pole) below the

release point (BRP), the output will source current (IOUT(L)
equal to the Hall-effect device operating current with the
current source turned off. The difference in the magnetic
operate and release points is the hysteresis (Bhys) of the
device. The hysteresis allows clean switching of the
output even in the presence of external mechanical vibra-
tion or electrical noise.

Powering up in the absence of a magnetic field (less
than BOP and higher than BRP) will allow an indeterminate
output state. The correct state is warranted after the first
excursion beyond BOP or BRP.

APPLICATIONS INFORMATION
External Components. It is strongly recommended
that an external bypass capacitor be connected (in close
proximity to the Hall element) between the supply and
ground of the device.
Power Derating. Due to the internal device power
dissipation, the junction temperature (TJ) will be higher
than the ambient temperature (TA). To ensure that the
absolute maximum junction temperature is not exceeded,
the following equations should be applied:
TJ = TA + (PD x RθJA)
where PD is the maximum supply power
I
OUT(H) x VCC
and RθJA is the package thermal resistance. The specified
limit for IOUT(H) should be used to ensure a margin of
safety.
Magnets. The simplest form of magnet that will operate
this device is a ring magnet. Other methods of operation,
such as linear magnets, are possible.
