DESCRIPTION
The APS11202 Hall-effect switch is an extremely temperaturestable and stress-resistant sensor IC, especially suited for operation
over extended temperature ranges (up to 150°C). Superior hightemperature 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 device includes, 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. 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.
