ATM90E25-YU-R

Overview

The ATM90E25-YU-R is a single-phase energy metering integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 1.8V to 3V and is housed in a 28-SSOP package suitable for industrial temperature conditions. The device functions as a current and power monitor with regulation capabilities, designed for precise energy measurement applications requiring low-power operation.

Feature Summary

• Provides accurate monitoring of current and electrical power parameters
• Integrates signal conditioning and regulation for stable operation
• Supports low-voltage operation compatible with modern embedded systems

Applications

• Single-phase smart metering infrastructure
• Industrial power monitoring equipment
• Energy management subsystems in consumer electronics

Procurement Notes

This component is classified as an End-of-Life (EOL) product. Availability is restricted, and procurement should focus on verifying the authenticity of remaining stock from authorized channels. Engineers must assess long-term supply chain risks and initiate replacement part selection immediately to ensure production continuity.

Selection Notes

Designers should evaluate alternative components from the same family or newer generations that offer similar single-phase metering capabilities. Considerations must include pin compatibility, software migration efforts, and updated regulatory compliance requirements when transitioning away from this discontinued part number.

Part Context

The ATM90E25 belongs to Microchip's ATM90E series of energy metering ICs. This specific variant targets cost-sensitive, low-power applications where high integration reduces external component count. It represents a specialized solution for measuring AC/DC parameters in compact form factors.
