A1184
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
a south polarity magnetic field of sufficient strength; and switches
LOW
field present.

a. Certain variants cited in this footnote are in production but have been determined to be LAST TIME BUY. This classification indicates that sale of this device is currently
restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable. Samples
are no longer available. Status change: October 31, 2006. Deadlilne for receipt of LAST TIME BUY ORDERS: April 27, 2007. These variants include: A1184EUA and
A1184LUA.
b. Certain variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of this device is
currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable.
Samples are no longer available. Status change: May 1, 2006. These variants include:A1184ELHLT and A1184LLHLT.

Mounting
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.
