ATT7053B/59S/59C, HT7017/HT7053C series of multi-functional, high-performance single-phase energy dedicated metering chips, using high-precision Sigma-delta ADC as metering input, the sampling rate can reach 31.2KHz, because the input channel supports independent and flexible gain configuration , an external manganin or current transformer can be used as a current sampling device. All measurement parameters can be directly output, and the peripheral MCU only needs to complete the management and communication protocol programs required by the multi-function electric 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 an application solution with complete functions and simple design for single-phase multi-function metering, which can fully meet the design requirements of single-phase multi-rate multi-function electric energy meters.
ATT7053B provides 3 channels of metering ADC input, provides two communication methods of SPI and UART, and is packaged in SSOP24.
ATT7059S provides 2 metering ADC inputs, only provides UART communication mode, SSOP16 package.
ATT7059C also adopts SSOP16 package, but it provides more IRQ (interrupt output) than ATT7059S, and one less GND.
The HT7053C operates at a wide voltage range of 3.0V~5.5V, provides 3 metering ADC inputs, 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-way metering ADC input, and only supports UART communication.
