LM3812M-7.0/NOPB

Current Regulation/Management Overview

The LM3812M-7.0/NOPB is a precision current gauge integrated circuit manufactured by Texas Instruments. It features an ultra-low loss sensing element and provides a PWM output for high-side current monitoring. The device is housed in an 8-SOIC package with dimensions of 0.154 inches (3.90mm width). It operates within a temperature range of -40°C to 125°C.

Current Regulation/Management Feature Summary

• Ultra-low loss sensing element for minimal voltage drop
• PWM output interface for digital current data transmission
• High-side current sensing capability

Current Regulation/Management Applications

• Evaluation using the LM3812EVAL-ND board
• High-side current monitoring systems
• Precision current regulation applications

Current Regulation/Management Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the 8-SOIC package type matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to 125°C aligns with your system's thermal environment before procurement.

Current Regulation/Management Selection Notes

Select this component when high-side current measurement with low insertion loss is required. The PWM output makes it suitable for microcontroller-based systems requiring digital current feedback. Consider the 8-SOIC package size for space-constrained designs. Verify compatibility with the intended evaluation board if prototyping.

Current Regulation/Management Part Context

This part belongs to the LM3812 series of current gauge ICs from Texas Instruments. It is functionally similar to the LM3812M-1.0/NOPB but differs in internal configuration or scaling factors associated with the '-7.0' designation. It serves as a specialized power management IC for precise current monitoring rather than general voltage regulation.

Current Regulation/Management Replacement Considerations

The LM3812M-1.0/NOPB is a related variant within the same family. Verify if the specific scaling or reference parameters of the '-7.0' version are critical for your application before substituting with other models.
