iC-PV: Battery-Buffered 40-Bit Multiturn Hall Encoder.
Developed for gearless multiturn encoders, iC-PV is a low-power Hall sensor based solution, which can be easily powered by a battery. Small and cost-effective, its low-consumption (10 µA from 3.0 to 5.5 V supply) makes it ideal as an alternative to mechanical gear multiturn solutions. The main features of iC-PV are:
Up to 40-bit revolution counting
Automatic switch to battery power when main power fails
Serial interface for connection with multiturn-enabled devices (e.g.: iC-LGC, iC-MHM, iC-MN, iC-MU)
Singleturn data input for devices without multiturn interface (e.g.: iC-LNB, iC-LNG)
Error signalling (configuration error, magnetic field monitoring, supply voltage monitoring)
iC-PV can also operate as a low-power (battery powered) 3-bit singleturn encoder with parallel output. With a voltage supply of 3.0 to 5.5 V and operating temperature
range of -40 to +125 °C, iC-PV is suitable for industrial application.
