CS5463-ISZ Datasheet PDF - Cirrus Logic

The CS5463-ISZ is a single-phase Power/Energy IC features a bi-directional serial interface for communication with a processor and a programmable energy-to-pulse output function. Additional features include on-chip functionality to facilitate system-level calibration, temperature sensor, voltage sag detection and phase compensation. The CS5463 is a CMOS monolithic power measurement device with a computation engine and an energy-to-frequency pulse output. The CS5463 is designed for power measurement applications and is optimized to interface to a current sense resistor or transformer for current measurement and to a resistive divider or potential transformer for voltage measurement. The current channel provides programmable gains to accommodate various input levels from a multitude of sensing elements.
