  • High-speed inductive resolver MLX90510

  • The MLX90510 is a high-speed inductive resolver IC used for absolute rotary motion/position sensing in safety critical automotive applications. Its main specifications benefit e-machine types of applications directly, and minimize the ECU effort required to get best-in-class accuracy under extreme mechanical and electrical conditions.

    The MLX90510 is designed to control an inductive transducer, process the captured analog sensor signal and provide differential Sine and Cosine outputs. The inductive sensor operation is based on the inductive coupling between a transmitting coil, the target and three receiver coils.

    With its innovative architecture, the MLX90510 brings several advantages:

    • The system propagation delay is trimmed to 0ns with a maximum of +/-120ns residual variations over the entire operating temperature range.
    • Input offset compensation and zero output-angle position adjustment are performed within the IC, lowering the effort on the ECU.
    • The 3-phase based coil design simplifies linearity optimization.
    • Decoupling between the input and output enables unprecedented EMC performances. It also ensures stable output amplitudes independently from the airgap related input signal strength.
    • The linearization feature, with up to 16 calibration points, deals with the non-linearities of challenging sensor modes like side-of-shaft.

    The MLX90510 has been developed as a SEooC (Safety Element out of Context) according to ISO 26262 and supports safety related system implementations up to ASIL C.

    For mass-production programming, the MLX90510 is compatible with the PTC04 (DB-HALL06, v3 or higher).

    Applications:

    • High speed absolute rotary position sensor
    • Motor position sensing (BLDC, PMSM, PMSR)
    • Traction motor
    • E-brake booster
    • Electric Power Steering (EPS)
  • 3D Magnetometer MX90392
    The MLX90392 is a 3D magnetometer especially designed for micropower cost-conscious applications and is available in versions:
    +/-5mT range for low-noise applications
    +/-50mT range for position sensor applications...

  • The MLX90392 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface. The device makes magnetic measurement along the 3 axis (X, Y being in a plane parallel to the surface of the die, Z being perpendicular to the surface). Those measurements and the IC temperature are converted into 16-bit words which are transferred upon request over I2C communication channel. The device transmits compensated raw measurement data.

    Especially designed for low micropower applications, the MLX90392 features a power down current of 1.5uA, and operates on a 1.8V supply.

    MLX90392 simplifies designs!
    To begin with, it reduces bill-of-materials costs and saves PCB space. Measuring just 2 mm x 2.5 mm x 0.4 mm, the sensor features a UTDFN-8 ultra-thin flat no-lead 8-pin package to help designers tackle space-constrained applications. To continue, the MLX90392 internal parameter can be updated on the fly from the microcontroller I2C bus, thus eliminating the need for an extra pin. Simpler PCB can be achieved. 
    And finally, the MLX90392 comes pre-programmed, making it a plug & play solution to integrate.

    The MLX90392 is available in 2 magnetic versions:
    +/-5mT range for low-noise applications
    +/-50mT range for position sensor applications

    Application Examples:

    • Power tools - Screwdriver trigger
    • Home security- door window intrusion
    • Knobs for White goods
    • PC peripheral – Mouse roller
    • Gaming joystick
    • Anti-tamper for energy metering
  • Triaxis® Magnetic Position Sensor MLX90421
    The MLX90421 reinvents the Triaxis® Magnetic Position Sensor. It provides Analog or PWM output. It distinguishes itself with functional safety, improved EMC, AMR and an extended operating temperature range....

  • The MLX90421 reinvents the Triaxis® Magnetic Position Sensor. It provides Analog or PWM output.

    Intended for use in cost-sensitive automotive applications including powertrain actuators, pedal positioning, fuel level gauges and transmission systems, though also suitable for industrial implementations, these ICs have superior capabilities in terms of functional safety, Absolute Maximum Ratings (AMR) and electromagnetic compliance (EMC) characteristics. They also support heightened temperature operation up to 160 °C

    The MLX90421 is pin-to-pin compatible with the previous generations of Triaxis® position sensor ICs.

    The MLX90421 is a monolithic magnetic position sensor IC. It consists of a Triaxis® Hall magnetic front end, an analog to digital signal conditioner, a DSP for advanced signal processing and a programmable output stage driver.

    The MLX90421 is sensitive to the three components of the magnetic flux density applied to the ICs (i.e. Bx, By and Bz). Programming the sensor determines which axes are used to calculate a rotation or linear position. This allows the MLX90421, with the correct magnetic design, to calculate the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees, see Figure 2 - Application Modes). It enables the design of non-contacting position sensors that are frequently required for both automotive and industrial applications.

    The MLX90421 provides ratiometric analog or pulse width modulated (PWM) outputs. Programming the sensor, after assembly into the application, increases the accuracy of the system thanks to the multi-point programmable linearization function.

    The MLX90421 is compatible with the PTC04 (DB-HALL06) for mass-production programming.
