A1250 2 - Hall-Effect Latch / Bipolar Switch FEATURES AND BENEFITS • AEC-Q100 automotive qualified • Quality managed (QM), ISO 26262:2011 compliant • High-speed 4-phase chopper stabilization • Low operating voltage down to 3 V • High sensitivity • Stable switch points • Robust EMC PACKAGES: 3-Pin SOT23W (suffix LH) 3-Pin SIP (suffix UA) Not to scale V+ VCC Regulator DESCRIPTION The A1250 Hall-effect sensor IC is a temperature-stable, stress-resistant bipolar switch. This device is the most sensitive Hall-effect device in the Allegro™ bipolar switch family and is intended for ring-magnet sensing. Superior high-temperature performance is made possible through an Allegro dynamic offset cancellation that utilizes chopper stabilization.
