Applications
The US2882LSE-AAA-000-RE is used in brushless DC motor commutation, end-of-travel position detection, and contactless switch applications where precise ±3mT magnetic switching thresholds are required. Its wide 3.5V to 24V supply range and 0 ppm/°C temperature stability make it well suited to automotive seat position sensors, industrial proximity switches, and appliance lid or door detection systems. The compact SOT23-3 footprint of 2.9mm x 1.6mm enables integration in space-constrained PCB designs near magnets and motor poles.

Frequently Asked Questions
What are the operate and release magnetic field thresholds for the US2882LSE-AAA-000-RE?
The US2882LSE-AAA-000-RE has an operate point (Bop) of 3mT and a release point (Brp) of -3mT, giving a symmetric 6mT hysteresis window. This bipolar threshold behavior ensures clean switching without output chatter when a magnet approaches and recedes from the sensor in motor commutation or door detection applications.
How does the 0 ppm/°C temperature coefficient of US2882LSE-AAA-000-RE benefit automotive and industrial designs?
The 0 ppm/°C temperature coefficient means the 3mT and -3mT switching thresholds remain constant from -40°C to 150°C without calibration compensation. In automotive seat sensors or industrial motor drives that experience wide temperature swings of 100°C or more, this eliminates threshold drift that would otherwise cause false triggering or missed commutation events.
What supply voltage range does the US2882LSE-AAA-000-RE support, and what protection features does it include?
The US2882LSE-AAA-000-RE operates from 3.5V to 24V, covering both 5V microcontroller systems and 12V or 24V industrial supply rails. It also integrates reverse voltage protection, which prevents device damage if the supply polarity is accidentally reversed during assembly or field wiring, improving system reliability without external protection diodes.
Which motor control or position sensing applications are most compatible with the US2882LSE-AAA-000-RE?
This device is ideal for BLDC motor commutation in power tools, cooling fans, and pump drives requiring 3 Hall sensors per motor to detect 60° or 120° rotor pole transitions at ±3mT fields. It also suits end-of-stroke detection in linear actuators and gear-tooth counters in automotive transmission position sensors needing sub-5ms response at up to 24V.
