Allegro MicroSystems announces the release of a new bipolar swap designed with a high rate chopping circuit to null out offsets along with dramatically improve changing repeatability. Allegro’s A1250 is an extremely temperature-stable and stress-resistant Hall-effect, the disease switch. This device is specially suited for operation over extended temperature ranges to +150°C. Superior high temperature functionality is made possible via dynamic offset cancellations, which reduces the residual offset voltage generally resulting from device overmolding, temp dependencies, and thermal tension. This new method is targeted at the automotive, industrial and buyer markets.

The A1250 style includes on a single silicon chip a existing regulator, Hall-voltage generator, small-signal amplifier, heli stabilization, Schmitt trigger, plus a short-circuit-protected, open-collector output. A south pole of enough strength will flip the output about. A north person of polish lineage is necessary to turn your output off.

The on-board regulator permits operation using supply voltages of 3.0 to 24 V. The advantage of running at 3.0 V is that it can be utilized in 3 V applications or additional external resistance could be added in series using the supply pin regarding greater protection in applications that can provide higher voltages.

Two package styles provide a magnetically optimized package for most applications. Package type LH is a modified SOT-23W area mount package, even though the UA package is a three-lead, ultra-mini-SIP pertaining to through-hole mounting. Each bundle type is only obtainable as lead (Pb) totally free (suffix, -T), with a 100% matte tin plated lead shape.
