The A3241 and A3242 integrated circuits are unipolar Hall-effect switches with
digital outputs. These sensors are suited for operation over extended temperature
ranges, up to +150°C. Superior high-temperature performance is made pos-
sible through an Allegro patented dynamic offset cancellation, which reduces
the residual offset voltage normally caused by device overmolding, temperature
excursions, and thermal stress.
The A3241 and A3242 Hall-effect switches include the following on a single
silicon chip: voltage regulator, Hall-voltage generator, small-signal amplier,
chopper stabilization, Schmitt trigger, and a short circuit protected open-drain
output. Advanced BiCMOS wafer fabrication processing is used to take advantage
of low-voltage requirements, component matching, very low input-offset errors,
and small component geometries.
The integrated voltage regulator permits operation from 3.6 to 24 V. The unipolar
family members operate with a sufcient south polarity eld only, turning off in
the absence of such a south polarity eld.
The A3241 and A3242 are rated for operation between the ambient temperatures
–40°C and 85°C for the E temperature range, and –40°C to 150°C for the L tem-
perature range. The small geometries of the BiCMOS process allow these devices
to be provided in ultrasmall packages. The package styles available provide mag-
netically optimized solutions for most applications. Package LH is an SOT23W,
a miniature low-prole surface-mount package, while package UA is a three-lead
ultramini SIP for through-hole mounting. Each package is available in a lead (Pb)
free version, with 100% matte tin plated leadframes.
