FEATURES AND BENEFITS - AEC-Q100 automotive qualified - High-speed, 4-phase chopper stabilization ▫Low switchpoint drift throughout temperature range ▫Low sensitivity to thermal and mechanical stresses - On-chip protection ▫Supply transient protection ▫Reverse-battery protection - On-board voltage regulator ▫3 to 24 V operation - Solid-state reliability - Robust EMC and ESD performance - Industry-leading ISO 7637-2 performance through use of proprietary, 40 V clamping structures PACKAGES: 3-pin ultra-mini SIP 1.5 mm × 4 mm × 3 mm (suffix UA) 3-pin SOT23-W 2 mm × 3 mm × 1 mm (suffix LH) DESCRIPTION The A1244 is a two-wire Hall-effect latch. The devices are produced on the Allegro™ advanced Bi CMOS wafer fabrication process, which implements a high-frequency, 4-phase, chopper stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh...
