CYD3144 Hall Effect Switch ICs |
 |
CYD3144E/L Hall-effect switch integrated
circuits for high temperature operating based on Hall-effect
principle, apply the semiconductor monolithic technology, which
includes a voltage regulator, Hall voltage generator, differential
amplifier, Schmitt trigger and an open-collector output on a single
silicon chip. ICs can convert the input magnetic field signal into
digital voltage output.

Cautions:
1) It is possible that outside mechanical stress affects the
operating point and the release point of Hall-effect circuit,
therefore, mechanical stress should be lessened as far as possible
in the process of assembly;
2) Pay attention to the soldering temperature at the leads; keep it
lower in a short time to guarantee good soldering quality.
