Allegro MicroSystems' A3281LUA-T is a Hall Effect digital switch latch featuring an open-collector output. This device is designed for applications requiring precise magnetic field sensing and latching functionality. It operates across a wide supply voltage range of 4.2V to 24V, with a maximum supply current of 8mA and a maximum output current of 25mA. The A3281LUA-T exhibits a sensing range of 9mT for trip and -9mT for release, and is polarized to respond to the south pole. Its 3-SIP (3-SSIP) package facilitates through-hole mounting. This component is suitable for demanding environments, operating within a temperature range of -40°C to 150°C. Common industry applications include position sensing, speed detection, and brushless DC motor commutation.
