LM3822MM-2.0/NOPB

Current Regulation/Management Overview

The LM3822MM-2.0/NOPB is a high-side current gauge regulator manufactured by Texas Instruments, designed for precise electrical current measurement and monitoring in power management applications. It operates within a supply voltage range of 2 V to 5.25 V and supports an operating temperature range from -40°C to +125°C. The device features a 2% accuracy rating and is housed in an 8-VSSOP surface-mount package.

Current Regulation/Management Feature Summary

• High-side current sensing capability for accurate monitoring
• Precision regulation with 2% accuracy specification
• Wide operating temperature range suitable for industrial environments

Current Regulation/Management Applications

• Power management system current monitoring
• Battery management systems
• Industrial control circuit protection

Current Regulation/Management Procurement Notes

Verify the specific suffix '2.0' indicates the 2% accuracy grade when ordering. Confirm the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Ensure the VSSOP-8 package variant matches the target PCB footprint requirements before finalizing procurement decisions.

Current Regulation/Management Selection Notes

Select this component when high-side current monitoring with tight tolerance is required. The 2% accuracy distinguishes it from standard variants. Consider the 8-VSSOP package for space-constrained designs. Verify input voltage limits do not exceed 5.25 V during system design phase.

Current Regulation/Management Part Context

This part belongs to the LM3822 family of current gauge regulators from Texas Instruments. It serves as a specialized analog circuit for precision current measurement, distinct from general-purpose switching regulators or controllers found in other PMIC lines.

Current Regulation/Management Replacement Considerations

Check for LM3822MM variants with different accuracy suffixes if 2% tolerance is not critical. Verify pin compatibility with alternative high-side current sensors from other manufacturers.
