A1210, A1211, A1212, A1213, and A1214
Continuous-Time Latch Family
FEATURES AND BENEFITS DESCRIPTION
AEC-Q100 automotive qualified The Allegro A1210-A1214 Hall-effect latches are next
generation replacements for the popular Allegro 317x and
Continuous-time operation
318x lines of latching switches. The A121x family, produced
Fast power-on time
with BiCMOS technology, consists of devices that feature fast
Low noise
power-on time and low-noise operation. Device programming
Stable operation over full operating temperature range
is performed after packaging, to ensure increased switchpoint
Reverse-battery protection
accuracy by eliminating offsets that can be induced by package
stress. Unique Hall element geometries and low-offset amplifiers
Solid-state reliability
help to minimize noise and to reduce the residual offset voltage
Factory-programmed at end-of-line for optimum
normally caused by device overmolding, temperature excursions,
performance
and thermal stress.
Robust EMC performance
The A1210-A1214 Hall-effect latches include the following on
High ESD rating
a single silicon chip: voltage regulator, Hall-voltage generator,
Regulator stability without a bypass capacitor
small-signal amplifier, Schmitt trigger, and NMOS output
transistor. The integrated voltage regulator permits operation
PACKAGES:
from 3.8 to 24 V. The extensive on-board protection circuitry
Not to scale
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.
NOT FOR
NEW DESIGN
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
3-pin SOT23W
most applications. Package LH is an SOT23W, a miniature low-
(suffix LH)
profile surface-mount package, while package UA is a three-lead
3-pin SIP, 3-pin SIP,
ultramini SIP for through-hole mounting. Each package is lead
matrix HD style chopper style
(Pb) free, with 100% matte-tin-plated leadframes.
