Hall-effect Latch Protects Against High Voltage Transients

摘要

Allegro Microsystems, Inc. announced a new, two-wire, Halleffect latch that is programmed at the factory to optimize the magnetic switch point accuracy. The A1244 Hall-effect latch uses the same high frequency, four-phase, chopper-stabilization technique that is used on complementary devices in this family (unipolar switches). Allegro's advanced BiCMOS wafer fabrication process is used to achieve magnetic stability over temperature and to eliminate offset inherent in single-element devices, when exposed to harsh-application environments.
