Last Time Buy

The A3283 part is in production but has been determined to be LAST TIME BUY. This classification indicates that the product is obsolete and notice has been given. Sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because of obsolescence in the near future. Samples are no longer available.

Date of status change August 16, 2010 Deadline for receipt of LAST TIME BUY orders October 29, 2010

Recommended Substitutions:

For existing customer transition, and for new customers or new applications, refer to the A1223. Note The A3280 and A3281 are obsolete. For existing customer transition, and for new customers or new applications, refer to the A1222.

NOTE For detailed information on purchasing options, contact your local Allegro field applications engineer or sales representative.

A3280, A3281, and A3283

Chopper-Stabilized, Precision Hall-Effect Latches

Packages:

Package LH

Package LT Not to scale

Package UA

Description The A3280, A3281, and A3283 Hall-effect latches are extremely temperature-stable and stress-resistant sensor ICs especially suited for operation over extended temperature ranges to +150°C. 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. 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 regulator permits operation with supply voltages of 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 lead Pb free suffix, with 100% matte tin leadframe plating.
