iC-RC1000 acts as an analog watchdog IC for industrial controllers and drive systems in the evaluation of sine encoders for SIL applications. From standstill to high speeds two diagnostic channels monitor the encoder signals to check whether they keep to the 1 V specification, signaling OK or ERROR to the controller independently of one another for safe error detection with the minimum circuitry.

iC-NQC: high-resolution sine interpolation provides memory expansion for sensor ID plate and OEM data via the serial BiSS C Interface

For the first time ever high-resolution sine-to-digital converter iC-NQC provides the microelectronics industry with a BiSS slave in C protocol that enables bidirectional data exchange with the existing device memory at the same time as the cyclic output of measurement data. Using normed addresses device information is available that indexes the relevant standard device profile or a description file. An optional electronic ID plate can also be used to describe the measurement application.

4–36 V buck/boost DC/DC converter with two programmable voltages ranging from 1.5 V to 5.5 V with very low residual ripple

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 of precision analog circuits.

The iC-LTA/iC-PT series: monolithically integrated speed and commutation encoders replace Hall encoders in brushless motors

The new optical sensors iC-LTA and the iC-PT series supply incremental and commutation signals in the smallest possible design space. They are based on a flat optoQFN that is a mere 0.9 mm thick with a ultrathin glass lid. The optimized phased array structure of the photochips means that a minimal scanning area of just 1.9 mm x 3.1 mm is enough to generate 2,500 pulses from a code disc measuring only 26 mm across, for example.
