90E25PYGI

Overview

The Microchip Technology 90E25PYGI is a single-phase energy metering integrated circuit designed for utility-grade power measurement applications. It operates within a supply voltage range of 2.8V to 3.6V and features an input impedance of 1kOhm or 50kOhm. The device achieves a measurement error of 0.5% and supports I/O voltage levels including 2.4V, 3.9V, and 6.2V for high-side, and 0.4V and 0.8V for low-side configurations. Packaged in a 28-SSOP format, it is optimized for accurate energy monitoring in single-phase systems.

Feature Summary

Provides precise single-phase energy metering with a specified measurement error of 0.5%
Supports flexible I/O voltage compatibility ranging from 0.4V to 6.2V
Operates on a low-voltage supply between 2.8V and 3.6V

Applications

Single-phase utility energy metering systems
Power quality monitoring devices
Smart grid infrastructure components

Procurement Notes

Verify the specific datasheet revision and pinout configuration before integration, as legacy documentation may vary. Confirm that the 28-SSOP package dimensions align with your PCB footprint requirements. Ensure the operating environment stays within the specified electrical limits for I/O voltages and supply rails to maintain the stated 0.5% measurement accuracy. Check for any export restrictions or compliance certifications required for your region.

Selection Notes

Select this component when designing single-phase metering solutions requiring high accuracy and low voltage operation. It is suitable for applications needing flexible interface voltages up to 6.2V. Consider the 28-SSOP package size for space-constrained designs. Verify that the 1kOhm or 50kOhm input impedance options meet the sensor interface requirements of the target system.

Part Context

This part belongs to Microchip's energy metering portfolio, specifically targeting single-phase measurement needs. It complements other utility-grade ICs by offering dedicated hardware for calculating active and reactive energy. The device is distinct from general-purpose microcontrollers, focusing solely on high-precision analog-to-digital conversion and energy calculation algorithms for power monitoring.
