iC-PVL is an ultra low power magnetic encoder, used for linear and off-axis multiturn position sensing. On main power failure, iC-PVL switches automatically to battery supply and continues scanning the position.iC-PVL operates with pole wheels or linear scales with a pole width of 1.0 mm up to 5.0 mm. Due to various operating modes, iC-PVL can work with iC-Haus singleturn encoders, as stand-alone SSI or incremental encoder, or links to embedded controllers via I2C.Features- Integrated Hall sensors with automatic gain and offset control- For magnetic scales of 1.0 up to 5.0 mm pole width- Current consumption of only 2 µA to 30 µA in typ. Applications- Tracking speed of up to 24 m/s (1.5 mm poles) or 15000 rpm (32 pole pairs)- Configurable multiturn counting up to 40 bits- Adjustable period count per revolution: FlexCount® logic for 1 to 256 pole pairs- Serial, parallel and incremental singleturn operating modes- SSI multiturn data output with error, warning, parity, and synchronization bits- Multiturn preset by pin or command- I2C master function for initial boot-up from EEPROM- I2C slave function for controller operation- Supply voltage of 3.0 V to 5.5 V- Automatic low-power operation on backup battery- Overspeed, battery and RAM (CRC) monitoring- Space-saving 16-pin QFN packageApplications- Absolute hollow-shaft position encoders- Gearless revolution counting- Linear position sensors- Metering applications- Battery-powered portable equipment
