Description
The A3280, A3281, and A3283 Hall-effect latches
are extremely temperature-stable and stress-resistant
sensor ICs especially suited for operation over extended
temperaturerangesto+150°C.Superiorhigh-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. 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-boardregulatorpermitsoperationwithsupplyvoltages
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-SIPfor through-hole mounting. Each package
type is lead (Pb) free (suffix, –T), with 100% matte tin
leadframe plating.
