NVE
Introduces Ultraminiature Wafer-Level Chip-Scale
Magnetic Switch Sensors
EDEN PRAIRIE, Minn.December
17, 2024NVE 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.

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 NVEs
