A1667LK-T Description

Short technical summary and product information.

The Allegro Microsystems A1667LK-T is a true zero-speed ring magnet sensor integrated circuit (IC) designed for digital ring magnet sensing applications. It utilizes an optimized Hall IC with a dual element Hall IC that switches in response to differential magnetic signals created by a ring magnet.

 

This sensor IC features robust performance with immunity against vibration and magnetic offset variation. It provides air gap independent switch points and a wide operating voltage range from 4V to 24V. The operating temperature range is -40°C to 150°C (TA), ensuring reliable performance in demanding environments.

 

The A1667LK-T comes in a 4-pin SIP (Single In-line Package) with through-hole mounting. The output type is Analog Voltage, and it has a typical current draw of 12mA. The sensing range is characterized by 70% trip and 30% release points, supporting both North and South pole detection.

 

Key applications include automotive transmissions, 2- and 3-wheeler speed sensing, and white goods drum speed applications. Its single-chip design ensures high reliability and a small mechanical size.
