Overview
The ATM90E26-YU-B is a single-phase energy metering integrated circuit manufactured by Microchip Technology. It operates within a voltage range of 2.8 V to 3.6 V and features an input impedance of 1 kOhm and 400 kOhm. The device achieves a measurement error of 0.5% and provides 16-bit DC resolution. It is housed in a 28-SSOP package with dimensions of 0.209 inches (5.30 mm) width. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- High-performance analog front-end designed for precise single-phase energy metering applications
- Supports two-wire and three-wire configuration topologies for versatile system integration
- Includes built-in anti-tamper detection capabilities to ensure data integrity and security
Applications
- Single-phase electricity meters
- Smart plug monitoring systems
- Energy management modules for residential utility infrastructure
Procurement Notes
Verify the specific suffix 'B' indicates tube packaging rather than reel or cut tape formats when sourcing. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure the design accommodates the 28-SSOP footprint and thermal requirements for the specified industrial temperature range.
Selection Notes
Select this component for designs requiring high accuracy in single-phase power monitoring. The 0.5% measurement error suits standard utility-grade applications. Consider the 28-SSOP package constraints for PCB layout. Verify compatibility with the required supply voltage range of 2.8 V to 3.6 V for the host microcontroller interface.
Part Context
This part belongs to the ATM90E26 series of energy metering ICs from Microchip Technology. It serves as a specialized solution for measuring electrical parameters in single-phase networks. The device integrates necessary signal conditioning and processing blocks to replace discrete analog components, simplifying the bill of materials for metering hardware.
Replacement Considerations
The ATM90E26-YU-R is a functional equivalent with identical electrical specifications but utilizes reel packaging instead of tubes. Verify that the change in physical packaging does not impact existing pick-and-place manufacturing processes.
