A1186
Description (continued)
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
and I
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

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: A1185ELHLT,
A1185EUA, A1185LLHLT, A1185LUA, A1186ELHLT, A1186EUA, A1186LLHLT, and A1186LUA.

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: A1145
and A1146.
