MULTIPLEXED
TWO-WIRE
HALL-EFFECT SENSOR ICs
The A3054KU and A3054SU Hall-effect sensors are digital mag-
netic sensing ICs capable of communicating over a two-wire power/
signal bus. Using a sequential addressing scheme, the device re-
sponds to a signal on the bus and returns the diagnostic status of the
IC, as well as the status of each monitored external magnetic field.
As many as 30 sensors can function on the same two-wire bus. This
IC is ideal for multiple sensor applications where minimizing the wiring
harness size is desirable or essential.
Each device consists of high-resolution bipolar Hall-effect switch-
ing circuitry, the output of which drives high-density CMOS logic
stages. The logic stages decode the address pulse and enable a
response at the appropriate address. The combination of magnetic-
field or switch-status sensing, low-noise amplification of the Hall-
transducer output, and high-density decoding and control logic is made
possible by the development of a new sensor DABiC (digital analog
bipolar CMOS) fabrication technology. The A3054SU is an improved
replacement for the original UGN3055U.
These unique magnetic sensing ICs are available in two tempera-
ture ranges; the A3054SU operates within specifications between
-20
°
C and +85
°
C, while the A3054KU is rated for operation between
-40
°
C and +125
°
C. Alternative magnetic and temperature specifica-
tions are available on special order. Both versions are supplied in
0.060" (1.54 mm) thick, three-pin plastic SIPs. Each device is clearly
marked with a two-digit device address (XX).
