The A3280--, A3281--, and A3283-- Hall-effect latches are extremely
temperature-stable and stress-resistant sensors especially suited for op-
eration over extended temperature ranges to +150°C. Superior high-tem-
perature performance is made possible through dynamic offset cancella-
tion, which reduces the residual offset voltage normally caused by device
overmolding, temperature dependencies, and thermal stress. The three
devices are identical except for magnetic switch points.
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-collector output to
sink up to 25 mA. A south pole of sufficient strength will turn the output
on. A north pole is necessary to turn the output off. An on-board regula-
tor permits operation with supply voltages of 4.2 to 24 volts.
Three package styles provide a magnetically optimized package for
most applications. Package type LH is a modified SOT23W surface-
mount package, LT is a miniature SOT89/TO-243AA transistor package
for surface-mount applications; while UA is a three-lead ultra-mini-SIP
for through-hole mounting. Each package type is also available in a lead
(Pb) free version (suffix, –T) , with a 100% matte tin plated leadframe.
