The new iC-PVS from iC-Haus is a universal Hall sensor IC for incremental or absolute position detection with a battery-buffered 56-bit position counter. For higher resolutions and highest requirements concerning signal conditioning, it can be easily expanded with the iC-TW29 as an interpolator IC thanks to the Sin/Cos interface.
The iC-PVS combines a flexibly configurable Hall array front-end with a 56-bit low-power period counter and an integrated 6-bit interpolator. Battery-buffered, it can be used to implement multi-turn absolute encoders that operate with conventional incremental scales or gear wheels. Due to the high mounting tolerances compared to classic absolute systems and freely scalable scanning diameters, the iC-PVS is an attractive alternative as a stand-alone solution for encoder systems with low to medium resolutions. Ultra-low power technology (2 to 30 μA) and an integrated battery monitor enable service-free operation for a minimum of 10 years.
iC-PVS supports pole wheels or linear scales with a pole width of 1.0 mm to 2.5 mm. Ferrous gear wheels with a gear module of 0.3 to 1.5 can be scanned using a back-bias magnet. With 128 signal periods, angular resolutions of 13 bits can be achieved.
Due to BiSS-C, SPI, and both incremental and analog sin/cos interfaces, iC-PVS allows for operation either as a stand-alone encoder solution or in combination with an interpolator IC such as iC-TW29. This enables much higher resolutions, and provides high-end signal conditioning (error compensation for amplitude, offset, phase error of the sin/cos track) and offers extended monitoring functions, for example for Predictive Maintenance applications for axle bearings in the context of Industry 4.0.
