ACS71020KMABTR-015B5-SPI

Overview

The ACS71020KMABTR-015B5-SPI is a single-phase, isolated power monitoring IC designed for AC/DC switching power supplies. It operates on a 5V supply with a maximum current consumption of 12mA. The device is housed in a 16-SOIC package (0.295 inch width) and supports surface mount installation. It functions within an operating temperature range of -40°C to +125°C. This component serves as a dedicated controller for power management applications.

Feature Summary

• Provides isolated power monitoring capabilities for single-phase systems
• Integrated SPI interface for digital communication and control
• Designed specifically for AC/DC switching power supply controllers

Applications

• AC/DC switching power supply controllers
• Single-phase isolated power monitoring systems
• Power management integrated circuits (PMIC)

Procurement Notes

Verify the specific suffix 'SPI' to confirm the serial peripheral interface protocol variant. Confirm the '015B5' designation matches the required isolation and accuracy specifications for the target design. Check the 'Not for New Designs' status if initiating a fresh project, as alternative components may be recommended by the manufacturer for future production runs.

Selection Notes

Select this component when a dedicated isolated power monitor with SPI connectivity is required for single-phase AC/DC conversion topologies. Ensure the system voltage aligns with the 5V supply requirement and that the 16-SOIC footprint fits the PCB layout constraints. Consider the wide operating temperature range for industrial or automotive environments where thermal stability is critical for power regulation accuracy.

Part Context

This part belongs to the ACS71020 family of power monitoring ICs from Allegro MicroSystems. These devices are engineered to provide precise measurement and control functions in power conversion systems. The series focuses on integrating isolation and digital interfaces to simplify the design of efficient and reliable power supplies for various electronic equipment.

Replacement Considerations

Official documentation suggests using the ACS37800 for new designs instead of this discontinued model.
