Description
The A1120, A1121, A1122, A1123, and A1125 Hall-effect,
unipolar switches are extremely temperature-stable and
stress-resistant sensor ICs, especially suited for operation
over extended temperature ranges to 150癈. Superior high-
temperature performance is made possible through dynamic
offset cancellation, which reduces the residual offset voltage
normally caused by device overmolding, temperature
dependencies, and thermal stress.
Each device includes on a single silicon chip a voltage regulator,
Hall-voltage generator, small-signal amplifier, chopper
stabilization, Schmitt trigger, and a short-circuit protected
open-drain output to sink up to 25 mA.
An on-board regulator permits operation with supply voltages
of 3 to 24 V. The advantage of operating down to 3 V is that
the device can be used in 3 V applications or with additional
external resistance in series with the supply pin for greater
protection against high voltage transient events.
For the A1120, A1121, A1122, and A1123 a south pole of
sufficient strength turns the output on. Removal of the magnetic
field turns the output off. The A1125 is complementary, in that
for these devices, a south pole turns the A1125 output off, and
removal of the magnetic field turns the output on.
Two package styles provide a magnetically optimized package
for most applications. Package type LH is a modified SOT23W,
surface mount package, while UA is a three-lead ultra-mini SIP
for through-hole mounting. Each package type is lead (Pb) free
(suffix, T), with a 100% matte tin plated leadframe.
