DESCRIPTION
The Allegro™ A1101-A1104 and A1106 Hall-effect switches are next
generation replacements for the popular Allegro 312x and 314x lines
of unipolar switches. The A110x family, produced with BiCMOS
technology, consists of devices that feature fast power-on time and
low-noise operation. Device programming is performed after
packaging, to ensure increased switchpoint accuracy by eliminating
offsets that can be induced by package stress. Unique Hall element
geometries and lowoffset amplifiers help to minimize noise and to
reduce the residual offset voltage normally caused by device
overmolding, temperature excursions, and thermal stress.
The A1101-A1104 and A1106 Hall-effect switches include the
following on a single silicon chip: voltage regulator, Hallvoltage
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 automotive and industrial motor commutation
applications, without adding external components. All devices in
the family are identical except for magnetic switchpoint levels.
The small geometries of the BiCMOS process allow these devices to
be provided in ultrasmall packages. The package styles available
provide magnetically optimized solutions for most applications.
Package LH is an SOT23W, a miniature lowprofile 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.
