Overview
The LM25056PSQ/NOPB is a single-phase system power measurement integrated circuit manufactured by Texas Instruments. It combines high-performance analog and digital technology with PMBus compliance for real-time monitoring of input voltage (VIN) and input current (IIN). The device operates within a supply voltage range of 3 V to 17 V and supports an operating temperature range from -40°C to +125°C. It is housed in a 24-WQFN package measuring 4x5 mm.
Feature Summary
- Integrates high-performance analog and digital technology for accurate power measurement
- Supports PMBus compliant communication for system configuration and monitoring
- Provides real-time monitoring capabilities for input voltage and current
Applications
- Single-phase energy metering systems
- System power management applications requiring PMBus interface
- Industrial equipment with real-time power monitoring needs
Procurement Notes
Verify the specific suffix 'PSQ' indicates the WQFN-24 package and commercial/industrial temperature grade. Confirm NOPB denotes lead-free and RoHS compliance. Ensure the ordering part number matches the required pinout and thermal pad configuration for the target PCB layout. Cross-reference the datasheet revision date to ensure compatibility with existing design documentation.
Selection Notes
Select this component when single-phase power measurement with digital interface is required. It is suitable for designs needing real-time VIN and IIN monitoring via PMBus. Consider the 24-WQFN package size for space-constrained layouts. Verify that the 3V to 17V supply range aligns with the system's available voltage rails.
Part Context
This IC belongs to the LM25056 family of system power measurement devices. It is designed for applications requiring precise energy metering and power management through a standardized digital interface. The device integrates necessary sensing and processing blocks to simplify the design of smart power monitoring solutions.
Replacement Considerations
Check for LM25056APSQ/NOPB if an automotive-grade variant is needed, as it shares similar functionality but may have different qualification standards. Verify pin-to-pin compatibility before substitution.
