Overview
The LB9051 is a Hall IC that is operated in the presence of
an alternating magnetic field and produces a digital output.
The LB9051 contains a silicon Hall generator, an amplifier, a Schmitt trigger circuit on chip and especially suited
for detection of magnetism (ex. detection of the rotation of
a small magnet-used substance).
Applications
• Detection of magnetism.
• Contactless switch.
• Detection of the rotation, position of a magnetic substance.
Features
• Operated in the presence of an alternating magnetic field.
• Wide operating voltage range (3.6 to 16V).
• Output capable of direct driving a TTL, MOS IC.
• High sensitivity (sensitive to low magnetism).
