3163
Suffix 'UA' Pinning
(ultra-mini SIP)
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擄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.
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 鈥楲T鈥?is a miniature SOT89/TO-243AA transis-
tor package for surface-mount applications; suffix 鈥楿A鈥?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').
