A3281LLT-T is a small, versatile, low power, CMOS integrated circuit that comes with a solid-state Hall-effect latch. It is designed primarily to open and close switches as needed by sensing the presence of a magnetic field. In the world of electronic components, these kinds of switches are commonly referred to as magnetic sensors or solid-state switches.

When a magnetic field is detected by the Hall-effect latch, the A3281LLT-T circuit will output either a logic low or a logic high voltage level, depending on the logic level of the particular configuration. This output can then be configured to control the operation of a device, or cascaded to other control circuits.

The A3281LLT-T is a cost-effective, reliable and versatile switch for applications such as automotive, security, consumer, industrial and commercial. It is also suitable for rotor position sensing, proximity sensing, current sensing, smart locks, alarm systems, pneumatic switches and many more. The A3281LLT-T can function in temperatures ranging from -40 to +125 degrees Celsius (-40 to +257 degrees Fahrenheit).

The A3281LLT-T has magnetic sensitivity of less than 10 Gauss and a quiescent (idle) current equivalent to 500 µA. Its wide operating voltage bandwidth ranges from 2.25V to 18V. It is also capable of providing ground fault protection and self-contained protection against magnetic field disturbances. In addition, it includes temperature compensation circuitry to ensure reliable output performance across a wide temperature range. Lastly, the device’s small dimensions (2.0mm x 2.0mm) make it an ideal fit for applications where the form factor is of great importance.

The A3281LLT-T also requires use of minimum external components. Thus, circuit complexity and development costs are minimized – wires are not needed to connect off-chip circuitry to the device. The A3281LLT-T is also ready to use upon application – no need to set up compensations.

In conclusion, the A3281LLT-T from Allegro MicroSystems is a great choice for a wide range of applications as a small and yet extremely reliable and budget-friendly magnetic sensor. It is capable of detecting ambivalent magnetic fields, and is suitable for working in wide range of temperatures. With its tiny form factor making it a perfect fit for numerous fields of application, it is the perfect solution for a wide range of requirements.
