The Allegro Microsystems A1156LUA-T is a two-wire, unipolar Hall-effect switch designed for automotive applications. It utilizes a high-frequency, 4-phase chopper-stabilization technique for magnetic stability across its operating temperature range of -40°C to 150°C.
This device features a current source output and operates on a supply voltage from 3V to 24V. Its sensing range is specified with a 6mT trip point and a 1mT release point. The A1156LUA-T is built on an advanced BiCMOS wafer fabrication process, ensuring solid-state reliability and robust performance.
Offered in a 3-pin SIP (Single Inline Package) for through-hole mounting, this component is suitable for cost-sensitive applications requiring fewer wires for operation compared to traditional open-collector switches. The integrated diagnostics capability, where output current levels indicate fault conditions, adds to its system design advantages.
Key features include on-chip protection for supply transients and reverse battery conditions, an on-board voltage regulator, and industry-leading ISO 7637-2 performance. The package is lead (Pb) free with 100% matte-tin leadframe plating.
