A1101, A1102, A1103, A1104, and A1106
Continuous-Time Switch Family
The Allegro
廬
A1101-A1104 and A1106 Hall-effect switches are next generation
replacements for the popular Allegro 312x and 314x lines of bipolar switches.
The A110x family, produced with BiCMOS technology, consists of devices that
feature fast power-on time and low-noise operation. Device programming is per-
formed after packaging, to ensure increased switchpoint accuracy by eliminating
offsets that can be induced by package stress. Unique Hall element geometries and
low-offset amplifiers help to minimize noise and to reduce the residual offset volt-
age 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, Hall-voltage generator, small-signal ampli-
fier, 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 鹵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 pro-
vided in ultrasmall packages. The package styles available provide magnetically
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 lead (Pb) free, with 100% matte
tin plated leadframes.
