Part # Distributor Manufacturer Product Category Description
MTD6502B Microchip Technology, Inc. Microchip Technology, Inc. Not Provided characteristics, while requiring no external tuning from the user. Speed control can be achieved through either power supply modulation or pulse-width-modulation (using the PWM digital input pin). Due to the compact packaging and minimum bill-of-material (power transistors incorporated, no Hall sensor...

  • First SOIC8-Packaged Hall-Effect Current Sensor With Integrated Current Path Introduced
    SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater sensitivity and accuracy. Available in both 15 A and 5 A versions, it measures bi-directional ac or dc currents by using a Hall-effect magnetic field sensor to measure the field generated by the current flow
  • Non-chopper-stabilized versus chopper-stabilized bipolor latching Hall-effect sensors
    Test results show significantly higher performance can be achieved using a quad hall element and proprietary programming without chopper stabilization.
  • Using the PIC18F2431 for Sensorless BLDC Motor Control
    also discussed the use of PIC18FXX31 devices to control a BLDC motor in both open loop and in closed loop using Hall effect sensors and quadrature encoders. This applications note describes BLDC motor speed control without the use of sensors.
  • Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function
    virtual neutral point to detect phases. The obvious cost advantage of sensorless the zero crossing points control is the elimination of the Hall position sensors. * Filtering the signals coming from the comparisons Although there are some disadvantages to sensorless using a majority function filter
  • Sensorless Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers
    environmental demands. they incorporate peripherals that are ideally suited for motor control, such as: This application note discusses implementation of a sensorless FOC algorithm for Permanent Magnet Syn- * Pulse-Width Modulation (PWM) (R) chronous Motors (PMSMs) using the Microchip dsPIC * Analog
  • Commutation of a BLDC Motor with Various Pole-Pairs Can Be Simplified By Using Absolute Encoder Feedback - White Paper (.pdf)
    fashion. Commutation of a brushless DC motor is dependent on the position of the rotor. It is essential to have feedback devices attached to the motor shaft to indicate the current rotor position to the controller. With various forms of feedback devices available, magnetic hall sensors and optical
  • Measure Angles on Rotating Systems with High Resolution
    integration of the Hall sensor and the encoder function onto a single silicon chip is now providing a lower cost solution. Using multiple Hall sensors on-chip allows signal processing with good noise immunity. The distance and angle information are output as sine and cosine signals. For rotating
  • High-five to high-side current sensing
    High-side current sensing detects downstream shorts and avoids many sources of electrical noise and EMI. This ACS754 Halleffect current sensor from Allegro Microsystems measures isolated high-side currents up to 200 A using less space than a quarter. An exploded view of an Allegro Microsystems
  • MICRO: Product Technology News
    times per nozzle, can be adjusted via the PLC terminal. Service areas can be accessed from the front, sides, and back of the system. All wetted materials are fireproof and acetone-proof. An analog absolute-linear-position sensor using proprietary magnetoinductive technology provides accurate
  • Medical Device Link .
    Characteristic M = M(H) for a superparamagnetic material. The advantages of using magnetic beads as labels in bioassays have been well established. Magnetic beads are not affected by reagent chemistry or photobleaching and are therefore stable over time. In addition, the magnetic background
