A1145 and
A1146
Ultrasensitive Two-Wire Chopper-Stabilized
Unipolar Hall Effect Switches
Description (continued)
feature on-chip transient protection and a Zener clamp to protect
against overvoltage conditions on the supply line.
The output currents of the A1146 switches HIGH in the presence
of a south (+) polarity magnetic field of sufficient strength, and
switches LOW otherwise, as in the presence of a weak field or a
north (–) polarity field. The A1145 has an opposite output: the
currents switch LOW in the presence of a south-polarity magnetic
field of sufficient strength, and switch HIGH otherwise.
Both versions are offered in two package styles. The LH is a SOT-
23W, miniature low-profile package for surface-mount applications.
The UA is a three-lead ultramini SIP for through-hole mounting.
Each package is available in a lead (Pb) free version (suffix, –T)
with 100% matte tin plated leadframe. Field-programmable versions
also available: A1185 and A1186.

1Pb-based variants are being phased out of the product line. 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: A1145ELHLT, A1145EUA, A1145LLHLT,
A1145LUA, A1146ELHLT, A1146EUA, A1146LLHLT, and A1146LUA.
