DESCRIPTION

The ATS19480 is a giant magnetoresistance (GMR) integrated

circuit (IC) that provides a user-friendly two-wire solution

for applications where speed 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 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

with ASIL 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 ATS19480 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
