CYD543 HALL-EFFECT
UNIPOLAR IC
SWITCHES |
 |
These Hall-effect switches are
monolithic integrated circuit consisting of a voltage regulator,
Hall-voltage generator, differential amplifier, Schmitt trigger,
temperature compensation circuit and open-collector output stage.
Its input is a magnetic flux density signal and output is a digital
voltage signal.
FEATURES
• Wide supply voltage range
• Fast response time
• Wide frequency and temperature range
• Long operating life
• Small size, convenient installing
• Output compatible with all digital logic families
• Unipolar Sensor
• ROHS Compliant
TYPICAL APPLICATIONS
• Contact-less switch
• Position control
• Speed measurement
• Revolution detection
• Isolation measurement
• Brushless dc motor
• Automotive igniters

Caution
1. When install, should as full as
possible decrease the mechanical stress acting on the Hall IC, to
avoid the influence of the operate point and release point.
2. On the premise of ensuring welding quality, use as possible as
low welding temperature an short time.
