Datasheet LF53464 (Littelfuse)

Omnipolar TMR
Datasheet LGA8L LF53464-08TMR
Omnipolar Magnetic Sensor
Description
The LF53464-08TMR angle sensor features a dual-axis, orthogonal push-pull Wheatstone bridge architecture. Each bridge integrates four high-sensitivity TMR (Tunnel Magnetoresistor) elements, delivering output voltage of up to 65% of the supply voltage. This strong signal output minimizes the need for external amplification or additional processing circuitry. The sensor also adjusts for ambient temperature variation. When a magnet is positioned above the sensor to create a magnetic field paral el to the chip surface, the chip’s dual-axis output produces voltage signals in a sine/cosine relationship proportional to the angle of the magnetic field. The LF53464-08TMR is offered in a compact LGA8L package, measuring 3 mm × 3 mm × 0.75 mm.
