NEW! High-Sensitivity
I²C Magnetometer
 
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 SM-Series magnetometers are factory calibrated to provide precise analog field measurements. The new part has an I²C interface and a programmable digital threshold output:

NEW! Current Sensor
Evaluation Board
 
A new isolated current sensor evaluation board allows you to test the remarkable ACT001-10E current sensor and a common application circuit.
AG974: ACT001 Eval Board

The ACT001-10E is a fully-isolated, inline current sensor with an on-chip current strap. A Wheatstone bridge manufactured with NVE’s state-of-the-art tunneling magnetoresistance (TMR) sensor elements detects the magnetic field from the input current across NVE’s unique polymer isolation barrier.

ACT001-10E Current Sensorr

Applications include:
  • AC and DC motor control
  • Power measurement
  • Overcurrent protection
  • Battery management systems

Key ACT001-10E specifications include:
  • ±500 mA linear range
  • 0.04 mV/V-mA sensitivity (typ.)
  • 0 to 14 V supply (no minimum)
  • Fully isolated
  • Ultraminiature 2.5 x 2.5 DFN6 package
