Vibration-Tolerant Hall Effect Transmission Speed And Direction Gear Tooth Sensor IC ATS19520LSNBTN-RSWHPYU
Description The A19520 is an advanced vibration-tolerant Hall-effect integrated circuit (IC) that measures the speed and direction of rotating targets. This sensor IC can directly measure ring magnets or be back-biased with a magnet to measure ferrous targets. The package features an integrated capacitor for electromagnetic compatibility (EMC). The A19520 employs intelligent algorithms that allow stable operation during vibration and highly dynamic air gap environments common to transmission applications. In addition, the A19520 differential sensing offers inherent rejection of interfering common-mode magnetic fields. Integrated diagnostics in the A19520 are used to detect an IC failure that impacts the output protocol’s accuracy, providing coverage for functional safety. The A19520 is provided in a 2-pin miniature SIP package (suffix UB) that is lead (Pb) free, with tin leadframe plating. The UB package includes an IC and capacitor integrated into a single overmolded package, with an additional molded lead-stabilizing bar for robust shipping and ease of assembly. A19520 was developed in accordance with ISO 26262:2011 as a hardware safety element out of context with ASIL B capability (pending assessment) for use in automotive safety-related systems when integrated and used in the manner prescribed in the applicable safety manual and datasheet. Top Features Differential Hall-effect sensor measures ring magnets and ferrous targets with inherent stray field immunity SolidSpeed Digital Architecture™ provides robust, adaptive performance with advanced algorithms that provide vibration immunity over the full target pitch Integrated solution includes a capacitor in a single overmolded miniature package Integrated diagnostics and certified safety design process Two-wire current source output pulse-width protocol supporting speed, direction, and error reporting EEPROM enables factory traceability Typical Applications Transmission EXPAND ×
