A1201, A1202, A1203, and A1204

Continuous-Time Bipolar Switch Family

Features and Benefits

▪ Continuous-time operation

▫ Fast power-on time

Description

The Allegro^®A1201, A1202, A1203, and A1204 Hall-effect

bipolar switches are next-generation replacements and

extension of the popular Allegro A3134, A3133, and A3132

▫ 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

by package stress. Unique Hall element geometries and low-

offset amplifiers help to minimize noise and to reduce the

residualoffsetvoltagenormallycausedbydeviceovermolding,

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

Packages: 3 pin SOT23W (suffix LH), and

3 pin SIP (suffix UA)
