Datasheet Summary
Powered by GS/AI

The ACS71020 is a single-phase, isolated AC power monitoring IC with voltage zero crossing and overcurrent detection, designed for use in AC-powered systems. It is provided in a 16-pin SOICW package and supports I2C or SPI digital interfaces. The device offers 16-bit ADCs for voltage and current measurement, user-programmable thresholds for overvoltage, undervoltage, and overcurrent via integrated EEPROM, and reinforced isolation rated up to 517 V RMS. The ACS71020KMABTR-030B3-I2C variant has a current sensing range of ±30 A and operates from a 3.3 V supply. The part is not for new design as of March 28, 2025, with replacement recommended as ACS37800.
