Description (continued)
field drops below the magnetic release point, B
the A3251 has the opposite polarity, switching HIGH in a south-
polarity magnetic field that B
field drops below B
The other differences in the devices are the power-on state. The
A3250 powers-on in the HIGH state, while the A3251 powers-on
in the LOW state.

Package
Three package styles provide a magnetically optimized package
for most applications. Type LT is a miniature SOT89/TO-243AA
surface mount package that is thermally enhanced with an
exposed ground tab, and type UA is a three-lead ultramini SIP
for through-hole mounting. The packages are lead (Pb) free, with
100% matte tin plated leadframes (suffix, –T).
