A1210, A1211, A1212, A1213, and A1214  
Continuous-Time Latch Family  
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  
Package LH, 3-pin Surface Mount  
can be induced by package stress. Unique Hall element geometries and low-offset  
3
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.
