Description

The A3280--, A3281--, and A3283-- Hall-effect latches are ex treme ly temperature-stable and stress-resistant sensors especially suited for operation over extended temperature ranges to +150°C. Superior high-temperature per for mance 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 iden ti cal except for mag net ic switch points.

Each device A3280--, A3281--, and A3283--  includes on a single silicon chip a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper sta bi li za tion, 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 regulator permits operation with supply voltages of 4.2 to 24 volts.

Three package styles provide a magnetically op ti mized pack age for most ap pli ca tions. Package type LH is a modified SOT23W surfacemount 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.
