The A1130LLHLX-T is a discontinued two-wire unipolar vertical Hall-effect switch with advanced diagnostics, designed for automotive applications requiring ASIL B compliance. It is packaged in a 3-pin SOT23W surface-mount configuration and operates with a junction temperature up to 165°C. The device supports operation down to 3 V, features integrated diagnostics, and meets AEC-Q100 and ISO 26262:2011 standards with load dump compliance up to 40 V and reverse-battery protection. Its typical supply current is 5.9 mA in the high state and 10.7 mA in the low state, with an ambient operating temperature range of -40 to 85°C. The sensing orientation is X, and it is designed for use in two-wire systems requiring diagnostic feedback.
