The LX3301A is an ideal solution for measuring mechanical
movement (linear, angular/rotation, and proximity) in a wide
variety of applications in automotive, industrial, aerospace,
and commercial applications including:
• Rotor position sensing (brushless DC motors)
• Robotic arm positioning
• Fluid level sensing
• Proximity detection (industrial automation)
• Gear position/travel (automotive)

The LX3301A includes integrated diagnostics features,
which regularly monitor various functions within the IC and
report conditions which are outside of specified parameters.
In the event of a detect failure, the device drives the output
to a pre-defined diagnostics level. The internal diagnostics
information can also be output via SENT-compatible
protocol for system development and debug purposes.
The LX3301A is compliant with ISO 26262 and rated for
ASIL C applications. Packaged in a 14-TSSOP package, the device
operates (to specification) from -40 to 125 °C and maintains full
functionality to 150 °C. The LX3301A is certified to AEC-Q100 grade 1.
