Two-Wire Hall-Effect Latch protects against voltage transients.January 9, 2012 -
Programmed at factory to optimize magnetic switch point accuracy, Model A1244 uses 4-phase, chopper-stabilization technique. BiCMOS wafer fabrication process achieves magnetic stability over temperature and eliminates offset inherent in single-element devices when exposed to harsh environments. Available package styles include SOT-23W miniature low-profile style for surface mount applications and TO-92 3-lead ultra-mini single inline package for through-hole mounting.

Allegro MicroSystems, Inc. Announces New Two-Wire, Hall-Effect Latch
Increased Protection Against High Voltage Transients
Worcester, MA - Allegro MicroSystems, Inc. announces a new, two-wire, Hall-effect latch that is programmed at the factory to optimize the magnetic switch point accuracy. The A1244 Hall-effect latch uses the same patented high frequency, 4-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.
The A1244 will be offered in two package styles. The "LH" is a SOT-23W style, miniature low profile package for surface-mount applications. The "UA" is a TO-92 style, three-lead ultra-mini single inline package (SIP) for through-hole mounting.
Additionally, the A1244 will have two ICC(low) options, similar to that of its predecessor; -I1: 5.0 to 6.9 mA, and -I2: 2.0 to 5.0 mA. The pricing stated below is in quantities of 1,000:
o A1244LLHLX-I2-T $0.58
o A1244LLHLX-I1-T $0.58
o A1244LLHLT-I1-T $0.60
o A1244LLHLT-I2-T $0.60
o A1244LUA-I1-T $0.61
o A1244LUA-I2-T $0.61
