ATT7059C

Product overview
        ATT7053B/59S/59C,HT7017/HT7053C series of multi-function, high performance single-phase electric energy metering ASIC, using high precision Sigma-delta ADC as measurement input ports, the sampling rate up to 31.2KHz, because the input channel gain configuration support independent and flexible, it can be connected with shunt or current transformer as current sampling device. All parameters can be directly read out, peripheral MCU only needs to complete the communication protocol and management procedures for the multi-function watt hour meter. All parameters are directly computed by the internal hardware algorithm, and fully guarantee the accuracy and reliability of the parameters. The series of chips for single-phase multi-function metering provides complete functions and simple design of application solutions, can fully meet the single-phase complex rate multi-function watt hour meter design requirements. 
      ATT7053B provides 3 way metering ADC input, providing SPI and UART two communication methods, SSOP24 package.



      ATT7059S provides 2way metering ADC input, Only providing UART communication method, SSOP16 package.
      ATT7059C also uses SSOP16 packages, but provides IRQ (interrupt output) more than ATT7059S, with fewer than 1 GND.
      HT7053C operating voltage is 3.0V~5.5V, wide voltage domain, providing 3 way metering ADC input, providing SPI and UART two communication methods, SSOP24 package.
      HT7017 is ATT7053C small package model, using SSOP16, providing 3 way metering ADC input, only support UART communication.
Basic characteristics
      Operating voltage range: 4.5V ~ 5.5V for ATT7053B
