The ATS19520 is an advanced Hall-effect integrated circuit (IC) that uses an integrated back-bias magnet to measure the speed and direction of rotating ferrous targets. The package features an integrated capacitor for electromagnetic compatibility (EMC).
Employing intelligent algorithms, the ATS19520 allows for stable operation during vibration and highly dynamic air gap environments common to transmission applications. In addition, the differential sensing offers inherent rejection of interfering common-mode magnetic fields.
The ATS19520 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.
The ATS19520 is provided in a 3-pin SIP package (suffix SN) that is lead (Pb) free, with tin leadframe plating. The SN package includes an IC, magnet, and capacitor integrated into a single overmold, with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.For applications that require no integrated magnet, please see the A19520. For applications that require a 3-wire speed and direction transmission gear tooth sensor, please see the ATS693.
