The A1642 is an optimized Hall effect sensing integrated circuit that provides a
user-friendly solution for true zero-speed digital ring-magnet sensing in two-wire
applications. This small package can be easily assembled and used in conjunction
with a wide variety of target shapes and sizes.
The integrated circuit incorporates a dual-element Hall effect sensor and signal
processing that switches in response to differential magnetic signals created by
ring magnet poles. The circuitry contains a sophisticated digital circuit to reduce
system offsets, to calibrate the gain for air-gap–independent switchpoints, and to
achieve true zero-speed operation. Signal optimization occurs at power-on through
the combination of offset and gain adjust and is maintained throughout the operat-
ing time with the use of a running-mode calibration. The running-mode calibration
allows immunity to environmental effects such as micro-oscillations of the target
or sudden air gap changes.
The regulated current output is con
fi
gured for two-wire applications and the
sensor is ideally suited for obtaining speed and duty cycle information in ABS
(antilock braking systems). The 1.5 mm spacing between the dual Hall elements is
optimized for
fi
ne pitch ring-magnet-based con
fi
gurations. For applications requir-
ing sensing of rotating ferrous gears and targets, refer to the ATS642LSH series of
products. The package is lead (Pb) free, with 100% matte tin leadframe plating.
