The A1184 device is a standard, two-wire, unipolar, Hall effect switches. The
operate point, B
OP
, can be field-programmed, after final packaging of the sensor
and placement into the application. This advanced feature allows the optimiza-
tion of the sensor switching performance, by effectively accounting for variations
caused by mounting tolerances for the device and the target magnet.
This family of devices are produced on the Allegro MicroSystems advanced
BiCMOS wafer fabrication process, which implements a patented, high-frequency,
chopper-stabilization technique that achieves magnetic stability and eliminates
the offsets that are inherent in single-element devices exposed to harsh applica-
tion environments. Commonly found in a number of automotive applications, the
A1184 is utilized to sense: seat track position, seat belt buckle presence, hood/
trunk latching, and shift selector position.
Two-wire unipolar switches are particularly advantageous in price-sensitive appli-
cations, because they require one less wire than the more traditional open-collec-
tor output switches. Additionally, the system designer gains inherent diagnostics
because output current normally flows in either of two narrowly-specified ranges.
Any output current level outside of these two ranges is a fault condition. The
A1184 also features on-chip transient protection, and a Zener clamp to protect
against overvoltage conditions on the supply line.
The output current of the A1184 switches
HIGH
in the presence of a south polarity
magnetic field of sufficient strength; and switches
LOW
otherwise, including when
there is no significant magnetic field present.
Both devices are offered in two package styles: LH, a SOT-23W miniature low-
profile package for surface-mount applications, and UA, a three-lead ultramini
Single Inline Package (SIP) for through-hole mounting. Each package is available
in a lead (Pb) free version (suffix,
–T
) with 100% matte tin plated leadframe.
Factory-programmed versions are also available. Refer to: A1140, A1141, A1142,
A1143, A1145, and A1146.
