HALL-EFFECT SWITCHES
The A3361x and A3362x Hall-effect switches are extremely
temperature-stable and stress-resistant sensors. Superior performance
over temperature is made possible through dynamic offset cancellation,
which reduces the residual offset voltage normally caused by device
overmolding, temperature dependencies, and thermal stress. The two
devices differ only in output polarity; the A3361x output current goes
low in the presence of a south pole of sufficient strength; the A3362x
output current goes high.
Each device includes on a single silicon chip a voltage regulator,
Hall-voltage generator, small-signal amplifier, chopper stabilization,
Schmitt trigger, and a constant-current open-collector output. An
on-board regulator permits operation with supply voltages of 3.5 to 24
volts. Noise radiation is limited by control of the output current slew
rate.
Three package styles provide a magnetically optimized package for
most applications. Suffix ‘xLH’ is a miniature low-profile surface-
mount package, ‘xLT’ is a miniature SOT-89/TO-243AA transistor
package for surface-mount applications; while suffix ‘xUA’ is a three-
lead ultra-mini-SIP for through-hole mounting.
