STPMS2H-PUR

Sensor And Detector Interfaces Overview

The STPMS2H-PUR is an application-specific standard product (ASSP) designed for high-precision measurement in power line systems. It functions as a smart sensor building block for single-phase or multi-phase energy meters, working in conjunction with the STPMC1 digital signal processor. The device supports medium to high-resolution monitoring of single or dual inputs using Rogowski coils, current transformers, Hall sensors, or shunts. Key electrical parameters include a VCC supply range of 3.2 V to 5.5 V and an internal low-drop regulator providing a typical 3 V output. It features two second-order sigma-delta modulators and a programmable chopper-stabilized amplifier. The STPMS2H variant meets IEC 62053-22 Class 0.2 specifications, ensuring accuracy within 0.5% error over a 1:5000 dynamic range at 50-60 Hz.

Sensor And Detector Interfaces Feature Summary

• Dual-channel architecture supporting simultaneous monitoring of voltage and current signals via integrated sigma-delta modulation.

Sensor And Detector Interfaces Applications

• Class 0.2 AC watt meters compliant with IEC 62053-22 standards
• Single-phase and multi-phase energy metering systems
• Smart grid infrastructure utilizing Rogowski coils or current transformers

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm Class 0.2 compliance and error margins. Ensure compatibility with the STPMC1 DSP for system integration. Confirm package type and RoHS status through authorized distributors. Validate that the 3.2 V to 5.5 V supply range matches the target application's power constraints.

Sensor And Detector Interfaces Selection Notes

Select the STPMS2H-PUR when Class 0.2 accuracy is required for energy billing applications. Choose this model over lower-class variants if the design demands a 1:5000 dynamic range with less than 0.5% error. Ensure the system utilizes the STPMC1 processor for optimal signal processing. Verify that the analog front-end requirements align with the integrated chopper amplifier capabilities.

Sensor And Detector Interfaces Part Context

The STPMS2 series serves as the analog front-end for STMicroelectronics' energy metering ecosystem. It pairs with the STPMC1 digital signal processor to form complete metering solutions. The 'H' suffix typically denotes higher precision classes compared to standard variants, targeting strict regulatory compliance for utility-grade electricity meters.

Sensor And Detector Interfaces Replacement Considerations

The STEVAL-IPE014V1 evaluation board utilizes the STPMS2L variant. Designers migrating from other models should verify pinout compatibility and ensure the replacement supports the required IEC 62053 class specifications for the target application.
