NANJING AH ELECTRONIC CO., LTD
AH6851 HALL-EFFECT SWITCH INTEGRATED CIRCUITS
These Hall-effect switch integrated circuits 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.

Cautions
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 as
short time.
