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.
