NVE Corporation Product Announcement

NVE Introduces Ultraminiature Wafer-Level Chip-Scale
Magnetic Switch Sensors

WLCSP
EDEN PRAIRIE, Minn.—December 17, 2024—NVE Corporation today announced several 1.5-volt magnetic switches in ultraminiature Wafer-Level Chip-Scale Packages (WLCSPs). The 0.65 by 0.65 millimeter packages makes the parts perfect for tight spaces and provide unmatched spatial sensitivity and precision.

Applications include precise industrial controls, gas and water meters, portable instruments, and single-cell battery or harvested power applications.

Unique Products

Magnetic switches turn on when a magnetic field is applied and turn off when the field is removed. Continuous-duty versions are available, as well as internally duty cycled versions that further reduce power consumption and allow virtually unlimited battery life. An integrated latch ensures the output is available continuously in duty-cycled versions.

The applied field can be of either polarity, and the operate points are extremely stable over supply voltage and temperature. The open-drain outputs sink up to 100 microamps.

Key specifications include:
   • Choice of magnetic operate points
   • 0.9 to 2.4 supply voltage for battery operation
   • Supply current as low as 95 nanoamps (duty-cycled versions)
   • –40 to 85 degree Celsius temperature range
   • Ultraminiature 0.65 by 0.65 millimeter four-pad solder-bumped WLCSP

Breakout Boards
Available 0.8 by 0.4 inch (21 by 10 millimeter) breakout boards have pre-soldered WLCSP sensors, 0.1-inch headers, and one-millimeter-pitch card-edge connectors.

There are four models of the new sensors in stock for immediate delivery, each with a breakout board.
 
The company plans to expand its line of WLCS sensors in the coming months, including 3.3-volt versions, 125 degree Celsius versions, and analog magnetic sensors.

More Information
A datasheet including the new WLCSPs is available. Visit NVE’s website for pricing and detailed technical information.
