South (+) magnetic fields must be of sufficient strength.
than the more traditional open-collector output switches. Additionally,
the system designer gains inherent diagnostics because output current
normally flows in either of two narrowly-specified ranges. This
provides distinct current ranges for I
OUT(H)
and I
OUT(L)
. Any output
current level outside of these two ranges is a fault condition.
Other features of the A1185 and A1186 devices include on-chip
transient protection and a Zener clamp on the power supply to protect
against overvoltage conditions on the supply line.
The output current of the A1186 switches HIGH in the presence of
a south polarity magnetic field of sufficient strength; and switches
LOW otherwise, including when there is no significant magnetic field
present. The A1185 has an inverted output current level: switching
LOW in the presence of a south polarity magnetic field of sufficient
strength, and HIGH otherwise.
Both devices are offered in two package styles: LH, a SOT-23W
miniature low-profile package for surface-mount applications, and
UA, a three-lead ultramini Single Inline Package (SIP) for through-
hole mounting. Each package is available in a lead (Pb) free version
(suffix, T) with 100% matte tin plated leadframe.
Factory-programmed versions are also available. Refer to: A1145
and A1146.
