MLX90293 Linear Hall Position Sensor IC Datasheet Description Features and Benefits The MLX90293 is a SMD Programmable Linear Hall Linear Hall Position Sensor IC Sensor IC that enables contact less position sensor Non-linear Magnetic Design with Linear Output applications. Signal Programmable Transfer Characteristic to The sensor measures the magnetic field component compensate system non-linearity and thermal perpendicular to the surface of the IC. The drift: MLX90293 supports multiple output modes, such as Over Position : 16 segments Piece-Wise- analog, PWM and SENT 2010. Linear The MLX090293 enables extensive nonlinear Thermal Drift over Temperature : Sensitivity optimization of the transfer characteristic. Such (1) and Offset : 6 segments - Piece-Wise-Linear optimization in turn enables simplified magnetic Selectable Output Mode: designs. The result is a linear output characteristic Analog (Ratiometric) over position after calibration. Pulse Width Modulation (PWM) The customer can program this relation in his end- SENT (according to SAE J2716-2010) of-line calibration through the connector with 12 bit Resolution - 10 bit Thermal Accuracy Melexis tooling. Open/Short Diagnostics Over-Voltage Protection Under-Voltage Detection 48 bit ID Number option AEC-Q100 Qualified Single Die SOIC-8 Package RoHS Compliant Dual Die (Full Redundant) TSSOP-16 Package RoHS Compliant SOIC-8 TSSOP-16 Applications Absolute Small Angle Rotary Position Sensor Absolute Small Stroke Linear Position Sensor Pedal Position Sensor Non-Contacting Potentiometer 1 IC is trimmed at Melexis to achieve minimized IC sensitivity & offset drift over temperature. Customers can trim the sensitivity & offset drift of the application over temperature.
