CS5460A-BS IC ? (SMD SSOP-24 Package) ? Single Phase Bi-Directional Power/Energy IC

CS5460A-BS IC is a highly integrated power measurement solution that combines two Analog-to-digital Converters (ADCs), high-speed power calculation functions, and a serial interface on a single chip. It is designed to accurately measure and calculate: Real (True) Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications. The CS5460A interfaces to a low-cost shunt resistor or transformer to measure current, and to a resistive divider or potential transformer to measure voltage. The CS5460A features a bi-directional serial interface for communication with a microcontroller and a pulse output engine for which the average pulse frequency is proportional to the real power. The CS5460A has on-chip functionality to facilitate AC or DC system-level calibration.

The CS5460A is a single-chip Delta-Sigma analog/digital converter (ADC) that integrates two Delta-Sigma ADCs, high-speed power calculation capabilities, and a serial interface. It is intended to precisely measure and compute energy, immediate power, IRMS, and VRMS for single-phase, two-wire, or three-wire power metering applications. To measure current, the CS5460A attaches to a low-cost shunt resistor or transformer, and to a resistant divider or potential transformer to monitor voltage. It has a bidirectional serial interface for communicating with a microcontroller, as well as a configurable frequency output that is proportionate to energy. The CS5460A includes on-chip capabilities for AC or DC framework calibration. The "Auto-Boot" functionality enables the CS5460A to operate independently and to initialise itself upon system power-up. The CS5460A reads dataset and begins giving??directives from an external EEPROM during Auto-Boot mode. In this mode, the CS5460A may operate without the need of a microprocessor, making it ideal for reduced cost??measuring purposes.
