ADE7953

Single Phase Multifunction Metering IC with Neutral Current Measurement
Manufactured by:

Product Details

The ADE7953 is a high accuracy electrical energy measurement IC intended for single phase applications. It measures line voltage and current and calculates active, reactive, apparent energy and instantaneous RMS voltage and current.

The device incorporates three sigma delta ADCs with a high accuracy energy measurement core. The third input channel simultaneously measures neutral current and enables tamper detection and neutral current billing. The additional channel incorporates a complete signal path that allows a full range of measurements. Each input channel supports independent and flexible gain stages making the device suitable for use with a variety of current sensors such as current transformers (CT’s) and low value shunt resistors. Two on-chip integrators facilitate the use of Rogowski coil sensors.

The ADE7953 provides access to on-chip meter registers via a variety of communication interfaces including SPI, I2C or UART. Two configurable low -jitter pulse output pins provide outputs that are proportional to active, reactive or apparent energy as well as current and voltage RMS. A full range of power quality information such as overcurrent, overvoltage, peak and SAG detection are accessible via the external IRQ pin. Independent active, reactive and apparent no-load detections are included to prevent meter ‘creep’. Dedicated reverse power (REVP), zero crossing voltage (ZX) and zero crossing current (ZX-I) pins are also provided. The ADE7953 energy metering IC operates from a 3.3V supply voltage and is available in a 28 pin LFCSP package.
