A3241 and A3242

Chopper-Stabilized

Unipolar Hall-Effect Switches

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.

Package LH, 3-pin Surface Mount

The A3241 and A3242 Hall-effect switches include the following on a single

silicon chip: voltage regulator, Hall-voltage generator, small-signal ampliﬁer,

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 sufﬁcient south polarity ﬁeld only, turning off in

the absence of such a south polarity ﬁeld.

Package UA, 3-pin SIP

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-proﬁle 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.
