Description (continued)
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
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
a south polarity magnetic field of sufficient strength; and switches

Sale of the variant is currently restricted to existing customer applications. The variant should not be purchased for new design applications because of obso-
lescence in the near future. Samples are no longer available. Status date change November 2, 2009. Deadline for receipt of LAST TIME BUY orders is April 30,
2010. Recommended substitute: for A1185LLHLT-T use 1185ELHLT-T, for A1186EUA-T for A1186LUA-T.

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-

(suffix, –T) with 100% matte tin plated leadframe.
Factory-programmed versions are also available. Refer to: A1145
