iC-Haus Announce Low Power 10-Bit Magnetic Encoder

The Ultra Low Power Single-Chip Hall Encoder iC-TW11 by iC-Haus allows for an energy-saving 10-bit angle detection and therefore targets for example battery-buffered applications.

With a sampling rate of 10 Hz an average current consumption of typically 3 µA is obtained. In standby mode between measuring cycles the idle current cuts back to approximately 100 nA.

In normal operation iC-TW11 supports sampling rates of 4 kHz with an activated filter and automatic amplifier gain for 10-bit resolution at maximum accuracy. A measuring cycle can be operated either via the SPI interface or via a separate trigger input by an external event.

A new position value is being signaled to the micro controller via interrupt. The 4-wire SPI interface can be operated with up to 16 MHz clock frequency. The interrupt structure allows a daisy chain wiring of multiple iC-TW11. Therefore a controller can capture multiple rotation axes simultaneously.

Typical applications are:

  • Battery-operated dynamic speed measurement in power tools
  • Position and motor control in mobile robots or airplanes
  • Wireless position measuring with “energy harvesting“ power supply
  • Mobile servo motor and stepper motor controls
  • Simple 10-bit encoder with adaptive current consumption
  • Digital control knob with high resolution and ultra-cap buffering
  • Manually adjustable digital potentiometer
  • Control knob with pushbutton function through evaluation of the magnetic field strength

At a voltage supply of 3.3 V (+/- 10 %) iC-TW11 operates in the extended industrial operating temperature range from -40 to +125 °C. The space requirement of the single-chip encoder iC is especially low due to the QFN16 package with 4 mm x 4 mm.
