Sanyo LB9051 Specifications
Ordering number:ENN2635
Monolithic Digital IC
LB9051
Switching Type Hall IC
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).
