A3291KUA-T Description

Short technical summary and product information.

The A3291KUA-T from Allegro MicroSystems is a precision Hall-effect latch designed for consumer and industrial applications. It operates over an extended temperature range from -40°C to 125°C, ensuring stability and resistance to physical stress and thermal variations.

 

This device integrates a voltage regulator, Hall voltage generator, amplifier, chopper stabilization, and a Schmitt trigger on a single silicon chip. It provides an open-drain output capable of sinking up to 25 mA. Operation requires a south polarity magnetic field to turn the output on and a north polarity field to turn it off. The supply voltage range is from 3V to 24V.

 

The A3291KUA-T is available in a 3-pin SIP package for through-hole mounting. Both packages are lead-free with 100% matte-tin leadframe plating, adhering to environmental standards.

 

Key specifications include symmetrical switchpoints, output short-circuit protection, and reverse battery protection, making it a reliable choice for applications such as industrial motor control, commutation sensing, and BLDC motors.
