The Allegro
A1201, A1202, A1203 and A1204 Hall-effect bipolar switches are
next-generation replacements and extension of the popular Allegro A3134, A3133,
and A3132 bipolar switch product line. Overall, the A120x family, produced with
BiCMOS technology, consists of continuous-time devices that feature fast power-
on time and low-noise operation. Device programming is performed after packag-
ing, to ensure increased switchpoint accuracy by eliminating offsets that can be
induced by package stress. Unique Hall element geometries and low-offset ampli-
fiers help to minimize noise and to reduce the residual offset voltage normally
caused by device overmolding, temperature excursions, and thermal stress.
The A120x Hall-effect bipolar switches include the following on a single silicon
chip: voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt
trigger, and NMOS output transistor. The integrated voltage regulator permits
operation from 3.8 to 24 V. The extensive on-board protection circuitry makes
possible a 30 V absolute maximum voltage rating for superior protection in auto-
motive and motor commutation applications, without adding external components.
All devices in the family are identical, except for magnetic switchpoints.
The small geometries of the BiCMOS process allow these devices to be pro-
vided in ultrasmall packages. The package styles available provide magnetically
optimized solutions for most applications. Package LH is a SOT23W, a miniature
low-profile surface-mount package, while package UA is a three-lead ultramini
SIP for through-hole mounting. Each package is lead (Pb) free, with 100% matte
tin plated leadframes.

Magnetic flux density, B, is indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity magnetic fields.
This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the field is indicated
by the absolute value of B, and the sign indicates the polarity of the field (for example, a 100 G field and a 100 G field have equivalent strength, but
opposite polarity).
