A19520: Vibration-Tolerant Hall Effect Transmission Speed and Direction Sensor IC

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.

The IC has been designed to a certified ISO 26262:2011 design process to allow easy integration into high safety level systems. Integrated diagnostics are used to detect an IC failure that impacts the output protocol’s accuracy, providing coverage compatible with ASIL B compliance.

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.
