HALL-EFFECT GEAR-TOOTH SENSORS  
—AC COUPLED  
The UGN/UGS3059KA and UGN/UGS3060KA ac-coupled Hall-  
effect gear-tooth sensors are monolithic integrated circuits that switch  
in response to changing differential magnetic fields created by moving  
ferrous targets. These devices are 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.

Both devices, when coupled with a back-biasing magnet, 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 devices’  
operating air gaps. 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 electromag-  
netic 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 regu-  
Dwg. PH-011  
lator, two quadratic Hall-effect sensing elements, temperature com-  
pensating 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.  
Pinning is shown viewed from branded side.  
The two devices provide a choice of operating temperature  
ranges. Both devices are packaged in a 5-pin plastic SIP.
