A1202 and A1203

Continuous-Time Bipolar Switch Family

DESCRIPTION

FEATURES AND BENEFITS

•ꢀ AEC-Q100 automotive qualified

•ꢀ Continuous-time operation

□ Fast power-on time

The Allegro^™A1202 and A1203 Hall-effect bipolar switches

are next-generation replacements and extension of the popular

Allegro A3133andA3132bipolarswitchproductline.Overall,

theA120xfamily,producedwithBiCMOStechnology,consists

□ Low noise

•ꢀ Stable operation over full operating temperature range

•ꢀ Reverse-battery protection

•ꢀ Solid-state reliability

•ꢀ Factory-programmed at end-of-line for optimum

performance

•ꢀ Robust EMC performance

of continuous-time 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.

•ꢀ High ESD rating

•ꢀ Regulator stability without a bypass capacitor

TheA120xHall-effectbipolarswitchesincludethefollowingon

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 motor commutation

applications, without adding external components.All devices

in the family are identical, except for magnetic switchpoints.

PACKAGES:

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

most applications. Package LH is a SOT23W, a miniature low-

profilesurface-mountpackage,whilepackageUAisathree-lead

ultramini SIPfor through-hole mounting. Each package is lead

(Pb) free, with 100% matte-tin-plated leadframes.
