ATT7053B Single-phase energy metering series IC

product description

ATT7053B/59S/59C, HT7017/ HT7053C series multi-function, high-performance single-phase electric energy dedicated metering chips, using high-precision Sigma-delta ADC as the metering input, the sampling rate can reach 31.2KHz, because the input channel supports independent and flexible gain configuration , can be connected with manganese copper or current transformer as a current sampling device. All measurement parameters can be directly output. The peripheral MCU only needs to complete the management and communication protocol procedures required by the multi-function energy meter. All parameters are directly calculated by the internal hardware algorithm, which fully guarantees the accuracy and reliability of the parameters. This series of chips provides a complete and simple application solution for single-phase multi-function metering, which can fully meet the design requirements of single-phase multi-rate multi-function energy meters.

ATT7053B provides 3-channel metering ADC input, provides two communication methods of SPI and UART, and is packaged in SSOP24.

ATT7059S provides 2-channel metering ADC input, only provides UART communication mode, SSOP16 package.

ATT7059C also adopts SSOP16 package, but provides IRQ (interrupt output) more than ATT7059S, and one less GND.

The working voltage of HT7053C is 3.0V~5.5V wide voltage range, it provides 3 channels of metering ADC input, and provides two communication methods, SPI and UART, and is packaged in SSOP24.

HT7017 is a small package model of ATT7053C, adopts SSOP16, provides 3 channels of metering ADC input, and only supports UART communication.
