DESCRIPTION
The APS12205, APS12215, and APS12235 Hall-effect sensor
ICs are extremely temperature-stable and stress-resistant
devices especially suited for operation over extended junction
temperature ranges up to 175°C. Superior high-temperature
performance is made possible through dynamic offset
cancellation, which reduces the residual offset voltage normally
caused by device overmolding, temperature dependencies, and
thermal stress.
The single silicon chip includes: a Hall plate, small signal
amplifier, chopper stabilization, Schmitt trigger, and a short-
circuit-protected open-drain output. A south pole of sufficient
strength turns the output on; a north pole of sufficient strength
is necessary to turn the output off. For applications requiring
operation from greater than 5.5 V or operation directly from
a battery, refer to the A1220, A1221, or A1223.
Two package styles provide a choice of through-hole or surface
mounting. Package type LH is a modified 3-pin SOT23W
surface-mount package, while UA is a three-pin ultramini SIP
for through-hole mounting. Both packages are lead (Pb) free,
with 100% matte-tin-plated leadframes.
