Allegro MicroSystems Inc. Programmable Linear W/Reverse Battery A1367LKTTG-2B-T

The Allegro A1367 is a programmable linear Hall-effect sensor IC designed for high-precision current sensing in automotive applications such as HEV inverters and electric power steering. It features a regulated supply with reverse-battery protection, a 240 kHz analog output bandwidth, and factory-programmed temperature compensation for ±1% accuracy across the -40°C to 150°C operating range. The device is packaged in a 4-pin SIP (suffix KT) with a 1 mm case thickness and is AEC-Q100 automotive qualified. Sensitivity is configurable between 0.6 and 6.4 mV/G via factory-set coarse programming bits, and the quiescent output voltage is user-adjustable. It includes output clamps for short-circuit diagnostics and open-ground detection for enhanced reliability.
