A3245

Chopper-Stabilized

Omnipolar Hall-Effect Switches

The A3245 integrated circuit is an omnipolar, ultrasensitive Hall-effect switch

with a digital output. This sensor has an integrated regulator permitting operation

to 24 V, making it the ﬁrst omnipolar switch available for operation to 24 V. This

device is especially suited for operation over extended temperature ranges, up

to +150°C. Superior high-temperature performance is made possible 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 A3245 Hall-effect switch includes the following on a single silicon chip:

voltage regulator, Hall-voltage generator, small-signal ampliﬁer, chopper stabiliza-

tion, 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 com-

ponent geometries.

The omnipolar operation of the A3245 allows activation with either a north or

a south polarity ﬁeld of sufﬁcient strength. In the absence of a magnetic ﬁeld,

the output is off. This patented magnetic-polarity-independence feature makes

this device an excellent replacement for reed switches, with improved ease of

manufacturing, because the A3245 does not require manufacturers to orient their

magnets. These devices allow simple on/off switching in industrial, consumer, and

automotive applications.

Package UA, 3-pin SIP

The A3245 is 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 temperature

range. The small geometries of the BiCMOS process allow these devices to be

provided in ultrasmall packages. The package styles available provide magneti-

cally 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.
