Description (continued)
The integrated circuit incorporates a dual-element Hall effect circuit
as well as signal processing that switches the output state in response
to changes in the magnetic gradients created by ferromagnetic
gear teeth. The circuitry contains a sophisticated digital circuit to
eliminate magnet and system offsets and to achieve true zero speed
operation (U.S. Patent 5,917,320). A-D and D-A converters are
used to adjust the device gain at power-on and to allow switching
independent of the breadth of the air gap.
The regulated current output is configured for two wire applications,
requiring one less wire for operation than do switches with the more
traditional open-collector output. The package is available in a lead
(Pb) free version, with 100% matte tin leadframe plating.
