The A3064LKA ac-coupled Hall-effect gear-tooth sensor is a
monolithic integrated circuit that switches in response to changing
differential magnetic fields created by moving ferrous targets. This
device is ideal for use in non-zero-speed, gear-tooth-based speed,
position, and timing applications such as in anti-lock braking systems,
transmissions, and crankshafts.
When coupled with a back-biasing magnet, the sensor can be
configured to turn on or off with the leading or trailing edge of a gear-
tooth or slot. Changes in fields on the magnet face caused by a moving
ferrous mass are sensed by two integrated Hall transducers and are
differentially amplified by on-chip electronics. This differential
sensing design provides immunity to radial vibration within the
device’s operating air gap. Steady-state magnet and system offsets are
eliminated using an on-chip differential band-pass filter. This filter
also provides relative immunity to interference from RF and electro-
magnetic sources. The on-chip temperature compensation and Schmitt
trigger circuitry minimizes shifts in effective working air gaps and
switch points over temperature, allowing operation to low frequencies
over a wide range of air gaps and temperatures.
Each Hall-effect digital Integrated circuit includes a voltage
regulator, two quadratic Hall-effect sensing elements, temperature
compensating circuitry, a low-level amplifier, band-pass filter, Schmitt
trigger, and an open-collector output driver. The on-board regulator
permits operation with supply voltages of 4.5 to 24 volts. The output
stage can easily switch 20 mA over the full frequency response range
of the sensor and is compatible with bipolar and MOS logic circuits.
The device is packaged in a 5-pin plastic SIP.
