ACS71020KMABTR-030B3-I2C

Overview

The Allegro MicroSystems ACS71020KMABTR-030B3-I2C is a single-phase, isolated power monitor and regulator designed for AC/DC switching power supplies. It operates within a supply voltage range of 2.97 V to 3.63 V and consumes a maximum operating current of 30 A. The device functions reliably across an extended temperature range from -40°C to +125°C. It utilizes a high-side sensing method and communicates via the I2C interface. The component is housed in a 16-SOIC wide package with a width of 7.50 mm (0.295 inches).

Feature Summary

• Provides electrical isolation for accurate power monitoring in AC/DC applications.
• Integrates I2C digital communication for system data retrieval.
• Supports high-side current sensing configurations.

Applications

• AC/DC switching power supply controllers
• Power management systems requiring isolated monitoring

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm interface type and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check manufacturer notices regarding obsolescence or design-in recommendations for newer alternatives.

Selection Notes

Select this component when isolated power monitoring with digital I2C output is required for AC/DC converters. Ensure the 16-SOIC footprint fits the PCB layout constraints. Validate that the 2.97 V to 3.63 V supply range matches the system voltage rails.

Part Context

This part belongs to the ACS71020 series of power monitors from Allegro MicroSystems. These devices are engineered for high-reliability industrial and commercial power conversion environments. The series emphasizes safety through galvanic isolation between the high-voltage sense path and the low-voltage control logic.

Replacement Considerations

Official documentation recommends using the ACS37800 series for new designs as a modern alternative to the ACS71020 family.
