CYD3141E SERIES
HALL-EFFECT SWITCH ICS |
 |
CYD3141E series 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.
