features on-chip transient protection and a Zener clamp to protect
against overvoltage conditions on the supply line.
The output currents of the A1141 and A1143 switch HIGH in the
presence of a south (+) polarity magnetic field of sufficient strength,
and switch LOW otherwise, as in the presence of a weak field or a
north (–) polarity field. The other two devices in the family (A1140
and A1142) have an opposite output: the currents switch LOW in
the presence of a south-polarity magnetic field of sufficient strength,
and switch HIGH otherwise. The other differences in the switches
are their defined low current levels and magnetic switchpoints.
All versions are offered in two package styles. The LH is a SOT-
23W, miniature low-profile package for surface-mount applications.
The UA is a three-lead ultramini SIP for through-hole mounting.
Each package is available in a lead (Pb) free version (suffix,
–T
)
with 100% matte tin plated leadframe. Field-programmable versions
also available: A1180, A1181, A1182, and A1183.
