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.
