NVE Introduces High-Sensitivity I²C Magnetometer

EDEN PRAIRIE, Minn.-March 28, 2022-NVE's groundbreaking line of Smart Magnetometers has been expanded with the SM223-a high-sensitivity version of the popular SM228 TMR magnetometer. Unique Tunneling Magnetoresistance (TMR) technology provides lower noise than Hall effect sensors and in-plane sensitivity.

All SMxxx magnetometers are factory calibrated to provide precise analog field measurements. The new part has an I²C interface and a programmable digital threshold output:
Key SM223 / SM228 specifications include:
• ±1.5 mT (SM223) or ±15 mT (SM228) range
• 2% of FS accuracy
• 15 kSps sample rate
• 2.2 to 3.6 volt supplies
• -40 to 125 °C temperature range
• Ultraminiature 2.5 x 2.5 TDFN6 package

Applications include:
• Proximity sensing
• Noncontact current sensing as low as 100 mA
• Automotive applications
• Cylinder position sensing
• Security and intrusion detection
