A1212LUA-T Datasheet PDF - Allegro MicroSystems

●The A1212LUA-T is a Hall-effect Latch of 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. 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. The integrated voltage regulator permits operation from 3.8 to 24V. The extensive on-board protection circuitry makes possible a ±30V 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 switch point levels.
