General Description
The Melexis US1881 is a Hall-effect latch designed in mixed signal CMOS technology.
The device integrates a voltage regulator ， Hall sensor with dynamic offset
cancellation system ，Schmitt trigger and an open-drain output driver ， all in
a single package.
Thanks to its wide operating voltage range and extended choice of temperature
range ， it is quite suitable for use in automotive ， industrial and consumer applications.
The device is delivered in a Thin Small Outline Transistor（TSOT） for surface
mount process and in a Plastic Single In Line （TO-92 flat） for through- hole mount.
Both 3-lead packages are RoHS compliant.
Detailed General Description
Based on mixed signal CMOS technology ， Melexis US1881 is a Hall-effect device
with high magnetic sensitivity. This multi-purpose latch suits most of the application
requirements.
The chopper-stabilized amplifier uses switched capacitor technique to suppress
the offset generally observed with Hall sensors and amplifiers. The CMOS technology
makes this advanced technique possible and contributes to smaller chip size and
lower current consumption than bipolar technology. The small chip size is also an
important factor to minimize the effect of physical stress. This combination results
in more stable magnetic characteristics and enables faster and more precise design.
The wide operating voltage from 3.5V to 24V ， low current consumption and large
choice of operating temperature range according to "L"， "K" and "E" specification
make this device suitable for automotive，industrial and consumer applications.
The output signal is open-drain type. Such output allows simple connectivity
with TTL or CMOS logic by using a pull-up resistor tied between a pull-up voltage
and the device output.
