The A3290KLHLX-T is a chopper-stabilized Hall-effect latch designed for consumer and industrial applications, featuring an open-drain output capable of sinking up to 25 mA. It operates from an unregulated supply voltage of 3 to 24 V and is rated for an ambient temperature range of -40°C to 125°C. The device is housed in a miniature SOT23W surface-mount package with 100% matte-tin plating and includes on-chip voltage regulation, reverse battery protection, and output short-circuit protection. The magnetic operate point ranges from 5 to 50 G for south polarity, with a release point of -50 to -5 G. Operation is enabled by dynamic offset cancellation for thermal stability and stress resistance. The part is not intended for automotive use.
