Digital feedback in the same cable and using the same connectors as motor power is a current trend in electrical drive systems. This single-cable approach simplifies system wiring and makes installation and maintenance easier. These advantages have already attracted the interest of both users and manufacturers.

iC-PVL, a configurable Hall multiturn encoder, is a battery-buffered, economical, and space saving replacement for mechanically geared multiturn encoders. Its low current consumption (<10μA) allows the battery to last several years. A flat QFN package is used, which is only 4x4 mm², and includes integrated Hall sensors. This allows the iC-PVL to read magnetic linear scales or tapes, or discs or magnet wheels with pole widths of 1.0 to ...

At SPS/IPC Drives 2015 in Nuremburg, iC-Haus will introduce its new encoder ICs which are described as blue, reflective and lensless. Specifically designed for flat encoders, with multiple diameters and line counts, the iC-PR reflective encoders feature dual analogue/digital output options, selectable interpolation factors and high resolution.

Recently released by iC-Haus, the iC-MH16 is a one-chip solution for magnetic sensor applications in fast motor control units.

The chip contains a Hall sensor array with signal amplification control, a FlexCount interpolator delivering incremental (ABZ) and latency-free commutation (UV...

A laser diode driver that permits MCU-based driving of laser diodes with common cathodes or P-type laser diodes in Continuous Wave (CW) mode has been introduced by iC-Haus. With the iC-HTP, either Automatic Power Control (APC), Automatic Current Control (ACC), or a full controller-based power regulation can be used.

A hall encoder, claimed to save energy, has been introduced by iC-Haus. The iC-TW11, which allows for a 10-bit angle detection, has a sampling rate and 10Hz, with an average current consumption of typically 3μA. In standby mode between measuring cycles the idle current cuts back to approximately 100nA. In normal operation the iC-TW11 supports sampling rates of 4kHz with an activated filter and automatic amplifier gain ...

For optical and magnetic length gauges featuring decimal gratings, the iC-MQF offers a sine resolution of up to 4000 edges. The circuit incorporates a signal conditioning analog front end, a vector-tracking converter for real-time conversion without latency, as well as fault-tolerant RS422 driver stages which output the incremental signals.

iC-Haus has today unveiled the new iC-HF, which provides 6 RS-422 line drivers for 3V – 5.5V encoder applications. Featuring an integrated Encoder Link function, the line drivers can be deactivated and analog/digital signals directly accessed through the line driver output pins. For differential RS-422 line driver operation, six differential complementary drivers are implemented.

iC-Haus have today announced new universal digital output drivers, iC-DX3 and iC-DXC3. The universal digital output drivers iC-DX3/DXC3 enable compact sensors to be equipped with NPN, PNP, push-pull, and IO link-compatible output driver options. From an input voltage of 8 to 30 V an integrated linear regulator provides the sensor electronics with a stable +3.3 V voltage and 10 mA loading.

PWM solenoid driver iC-GE and iC-GE100 enable the optimum energizing of magnetic solenoids in valves, relays, and other actuators, thus saving power. The solenoids are driven by a regulated current of between 100 mA and 1 A (iC-GE100: 10 to 100 mA). Active power control permits the devices to be used in a wide supply voltage range of between 10 and 36 V.

The cascadable demo board NQ6D for the evaluation of angle sensors and encoders comes with the advanced sine-to-digital converter iC-NQC.

From just one chip and a variable input voltage of 4 V to 36 V iC-DC generates two stabilized output voltages that can be adjusted between 1.5 V and 5.5 V for the compact voltage supply of industrial sensors and small subsystems. The combination of switching converter plus two back-end linear regulators minimizes the amount of space required for the power pack and achieves a good residual ripple of typically 10 mVpp – ideal for the supply o...
