The ATS19580 is a giant magnetoresistance (GMR) integrated circuit (IC) that provides a user-friendly two-wire solution for applications where speed and direction information is required using ferromagnetic gear tooth targets. The fully integrated package includes the GMR IC, a protection capacitor for EMC robustness, and a back-bias magnet in a single-in-line package.
The GMR-based IC is designed for use in conjunction with ferromagnetic gear tooth targets and is orientation compatible with Hall-effect technology. The fully integrated solution senses at large operating air gaps and over a large air gap range. State-of-the-art GMR technology on a monolithic IC with industry-leading signal processing provide accurate speed and direction information in response to low-level differential magnetic signals. The differential sensing offers inherent rejection of interfering common-mode magnetic fields.
集成诊断用于检测IC故障，会影响输出协议的准确性，提供与ASIL B兼容的覆盖范围，内置于EEPROM划痕内存，可在整个IC的产品生命周期内提供该设备的可追溯性。根据应用程序的需求，可以将ASIL报告作为产品提供或禁用。亚博尊贵会员
The ATS19580 is provided in a lead (PB) free 3-pin SIP package with tin lead frame plating. The SN package includes a GMR IC, a magnet, and capacitor integrated into a single over-mold, with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.
