ATS19580

Large Air Gap, GMR Transmission Speed and Direction

Sensor IC for Gear Tooth Sensing

FEATURES AND BENEFITS

DESCRIPTION

• Fully integrated solution has GMR IC, protection

capacitor, and back-bias magnet in a single in-line

overmolded package

• Innovative GMR technology provides large operational

air gap sensing on ferromagnetic targets

• Advanced algorithms for flexible design-in and system

compensation

TheATS19580 is a giant magnetoresistance (GMR) integrated

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

applicationswherespeedanddirectioninformationisrequired

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.

□ Advanced vibration algorithms guarantee valid

direction information

□ Automatically adapts to extreme mechanical changes

(air gap) and thermal drifts

• Measures differentially to reject common-mode stray

magnetic fields

• Orientation compatible with Hall-effect technology

• Integrated ASIL diagnostics and certified safety design

process (optional fault reporting)

withASILB(assessmentpending). Built-inEEPROMscratch

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.

PACKAGE: 3-pin SIP (suffix SN)

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.
