CYD512 Latching Hall-effect ICs |
|
CYD512 Hall Effect latch ICs are
composed of a reverse protector, voltage regulator, Hall voltage
generator, differential amplifier, Schmitt trigger and an
open-collector output (bipolar latch) on a single silicon chip. ICs
can convert the changeable 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, and keep
it lower in a short time to guarantee good soldering quality.
