Custom Made SuitPress Release Release date: June 3, 2008 Allegro Microsystems, Inc. Announces New General-Purpose Latchesfor Non-Automotive Applications Small, Robust Packages with Reverse Battery Protection Worcester, MA - June 3, 2008 - Allegro MicroSystems, Inc. hasreleased two new temperature-stable and stress-resistantHall-effect latches, especially suited for operation in consumerand industrial products. Superior high-temperature performance ismade possible through Dynamic Offset Cancellation, which reducesthe residual offset voltage normally caused by device packageovermolding, temperature dependencies, and thermal stress. The twodevices are targeted at non-automotive applications and areidentical except for their magnetic switchpoints. Both devices include, on a single silicon chip, a voltageregulator, a Hall-voltage transducer, a small-signal amplifier,chopper stabilization, a Schmitt trigger, and a short-circuitprotected open-collector output to sink up to 25 mA. A southpolarity magnetic field of sufficient strength is required to turnthe output on. A north polarity field of sufficient strength isnecessary to turn the output off. An onboard regulator permitsoperation with supply voltages in the range of 4.2 to 24 volts withan operating temperature range of -40
