DESCRIPTION
The APS12202 and APS12212 Hall-effect latches are extremely
temperature-stable and stress-resistant sensor ICs, especially
suited for operation over extended temperature ranges (up to
150°C). Superior high-temperature performance is made possible
through dynamic offset cancellation, which reduces the residual
offset voltage normally caused by device package overmolding,
temperature dependencies, and thermal stress. The two devices
are identical except for their magnetic switch points.
Both devices include, on a single silicon chip, a voltage regulator,
a Hall voltage generator, a small-signal amplifier, chopper
stabilization, a Schmitt trigger, and a short-circuit protected
open-drain output to sink up to 25 mA. A south polarity magnetic
field of sufficient strength is required to turn the output on. A
north polarity field of sufficient strength is necessary to turn
the output off. An onboard regulator permits operation with
supply voltages in the range of 3 to 24 V.
Two package styles provide a magnetically optimized package for
most applications: type LH is a miniature SOT23W low-profile
surface-mount package, and type UA is a three-pin ultramini
SIP for through-hole mounting. Both packages are lead (Pb)
free with 100% matte-tin leadframe plating.
