Allegro 霍尔传感器 A1212LUA
Description
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 normally 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 provided 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.
