Introducing the new ACT001-10E TMR Isolated Current Sensor from NVE. This is a high-sensitivity, inline analog TMR current sensor for AC or DC measurements.
The ACT001-10E is an ideal replacement for the recently discontinued NVE AAV003-10E GMR current censor.
The part is in an ultraminiature 2.5 x 2.5 mm DFN6 package with an integrated current strap. A Wheatstone bridge configuration provides a bipolar differential output proportional to the current through the strap
Key ACT001-10E specifications include:
- ±500 mA linear range
- 0.04 mV/V-mA sensitivity (typ.)
- 0 to 14 V supply (no minimum)
- Ratiometric output
- Fully isolated
- -40 to 125 °C temperature range
- Ultraminiature 2.5 x 2.5 x 0.8 mm DFN6 package
- AC and DC motor control
- Power measurement
- Overcurrent protection
- Battery management systems
