The Allegro
A1210-A1214 Hall-effect latches are next generation replacements
for the popular Allegro 317x and 318x lines of latching switches. The A121x
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 low-offset
amplifiers help to minimize noise and to reduce the residual offset voltage nor-
mally caused by device overmolding, temperature excursions, and thermal stress.
The A1210-A1214 Hall-effect latches 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
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.
