S-57TZ S Series AUTOMOTIVE, 150C OPERATION, HIGH-WITHSTAND VOLTAGE, HIGH-SPEED, www.ablic.com TM ZCL HALL EFFECT IC ABLIC Inc., 2019-2021 Rev.1.2 00 This IC, developed by CMOS technology, is a high-accuracy Hall effect IC that operates with high temperature and high-withstand voltage. The IC switches output voltage level when the IC detects magnetic flux density (magnetic field) polarity changes. The ZCL (Zero Crossing Latch) detection method realizes polarity changes detection with the higher accuracy than the conventional bipolar latch method. Using this IC with a magnet makes it possible to detect the rotation status in various devices. ABLIC Inc. offers amagnetic simulation servic that provides the ideal combination of magnets and our Hall effect ICs for customer systems. Our magnetic simulation service will reduce prototype production, development period and development costs. In addition, it will contribute to optimization of parts to realize high cost performance.
