The unipolar switching characteristic makes this device ideal for use with a simple bar or rod magnet. The A3163ELT and A3163EUA are identical except for package. Each device includes a voltage regulator for operation with supply voltages of 3.5 to 24 volts, reverse-battery protection, quadratic Hallvoltage generator for low offset, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and a constant-current opencollector 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 transistor 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').

MH-008-8A 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. Suffix “UA” ACTIVE AREA DEPTH 0.0195" 0.50 mm NOM 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 vibration or electrical noise. 0.080" 2.04 mm 0.056" 1.44 mm A BRANDED SURFACE 1 2 3 +I Dwg.

GH-007-8 5 3163 HALL-EFFECT SWITCH FOR 2-WIRE APPLICATIONS 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 IOUT(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. 'UA' PACKAGE – + 3 2 X 0.95 V 0.1 µF 100 Ω 1 SUPPLY Dwg.
