Allegro MicroSystems A1202EUA-T is a Hall Effect latching digital switch designed for precise magnetic field detection. This component features an open-drain output and operates with a supply voltage range of 3.8V to 24V, drawing a maximum of 7.5mA quiescent current. The A1202EUA-T exhibits robust latching functionality, activating with the dominant pole (North or South) and remaining active until the opposite pole is applied. Its sensing range is specified at 7.5mT for trip and -7.5mT for release, ensuring reliable operation in various magnetic environments. The device is packaged in a 3-SIP configuration, suitable for through-hole mounting. Typical applications include position sensing, speed detection, and brushless DC motor commutation across industrial and automotive sectors. The part is supplied in bulk packaging.
