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

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.
