Ultraminiature
WLCSP Magnetic Switch Sensors
We
are introducing several 1.5-volt magnetic switches in ultraminiature WLCS
packages (WLCSP). The 0.65 mm package makes them perfect for tight spaces
and provides 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 nA (duty-cycled versions)
40 to 85 °C temperature range
Ultraminiature 0.65 x 0.65 mm four-pad solder-bumped
WLCSP
Breakout Boards
Available 0.8 x 0.4 inch (21 x 10 mm) breakout
boards have pre-soldered WLCSP
sensors, 0.1" headers, and 1 mm-pitch card-edge connectors.
These are the four new sensors and their breakout boards:
This video shows the ridiculously small size and amazingly low power of one of
these sensors:
