DESCRIPTION
TheATS19580 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 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 provides 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.
Integrated diagnostics are used to detect an IC failure that would
impact output protocol accuracy, providing coverage compatible
withASIL B (assessment pending). Built-in EEPROM scratch
memory offers traceability of the device throughout the IC’s
product lifecycle. ASIL reporting can be enabled or disabled
as a product offering depending on the applications’ needs.
The ATS19580 is provided in a lead (Pb) free 3-pin SIP
package with tin leadframe plating. The SN package includes
a GMR IC, a magnet, and capacitor integrated into a single
overmold, with an additional molded lead-stabilizing bar for
robust shipping and ease of assembly.
