A1180, A1181,
A1182, and A1183
Sensitive Two-Wire Field-Programmable
Chopper-Stabilized Unipolar Hall Effect Switches
Description (continued)
wire than the more traditional open-collector output switches.
Additionally, the system designer gains inherent diagnostics
because output current normally ows in either of two narrowly-
specied ranges. Any output current level outside of these two
ranges is a fault condition. The A1180-83 family of devices also
features on-chip transient protection, and a Zener clamp to protect
against overvoltage conditions on the supply line.
The output currents of the A1181 and A1183 switch HIGH in the
presence of a south polarity magnetic eld of sufcient strength;
and switch LOW otherwise, including when there is no signicant
magnetic eld present. The A1180 and A1182 have inverted out-
put current levels: switching LOW in the presence of a south polar-
ity magnetic eld of sufcient strength, and HIGH otherwise. The
devices also differ in their specied LOW current supply levels.
Both devices are offered in two package styles: LH, a SOT-23W
miniature low-prole 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 (sufx, –T) with 100% matte tin plated leadframe.
Factory-programmed versions are also available. Refer to: A1140,
A1141, A1142, A1143, A1145, and A1146.

3This variant is in production, however, it has been deemed Pre-End of Life. The product is approaching end of life. Within a minimum of 6 months, the device
will enter its final, Last Time Buy, order phase. Status change: January 31, 2011. Suggested replacement: A1190LLHLX-T.
4Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of the variant is currently restricted to
existing customer applications. The variant should not be purchased for new design applications because obsolescence in the near future is probable. Samples
are no longer available. Status change: January 31, 2011.
