The A1145EUA-T is a discontinued two-wire, unipolar Hall effect switch designed for automotive sensing applications such as seat track position and seat belt buckle detection. It features chopper stabilization for low switchpoint drift over temperature and includes on-chip protection against supply transients and reverse battery conditions, operating from 3.5 V to 24 V. The device is packaged in a 3-pin SIP (ultramini SIP) for through-hole mounting, with an operating ambient temperature range of -40°C to 85°C. The output switches low in the presence of a sufficient south-polarity magnetic field. This variant is classified as not for new design, and samples are no longer available.
