A1184
Standard Two-Wire Field-Programmable
Chopper-Stabilized Unipolar Hall Effect Switch
Description (continued)
of two narrowly-specified ranges. Any output current level outside
of these two ranges is a fault condition. The A1184 also features
on-chip transient protection, and a Zener clamp to protect against
overvoltage conditions on the supply line.
The output current of the A1184 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.
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: A1140,
A1141, A1142, A1143, A1145, and A1146.
