LTC4151IDD#TRPBF

Power Supply Controllers, Monitors Overview

The LTC4151IDD#TRPBF is a high-side power monitor manufactured by Analog Devices Inc., designed for precise current and voltage monitoring in systems operating within a wide input voltage range of 7V to 80V. This component integrates an on-board 12-bit analog-to-digital converter (ADC) to facilitate accurate data acquisition without requiring external precision components. It communicates via an I2C interface, allowing for flexible configuration and real-time monitoring of power parameters. The device is housed in a compact 10-lead DFN package, suitable for surface-mount applications where space efficiency and thermal performance are critical.

Power Supply Controllers, Monitors Feature Summary

• Integrates a 12-bit ADC for direct digital conversion of monitored signals
• Supports I2C communication for system integration and control
• Operates across a wide high-voltage input range up to 80V

Power Supply Controllers, Monitors Applications

• High-side current sensing in industrial power systems
• Battery management systems requiring voltage monitoring

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the IDD variant corresponds to the industrial temperature range and DFN-10 package type required for your design. Ensure compatibility with your I2C bus voltage levels and check for any recent product change notices from Analog Devices regarding pinout or electrical specifications before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when high-side monitoring is required for voltages exceeding standard low-voltage IC limits. The integrated 12-bit resolution provides sufficient accuracy for most general power monitoring tasks. Consider the DFN-10 footprint constraints and ensure adequate thermal relief on the PCB. Verify that the I2C address configuration meets your system's addressing requirements.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC4151 series of high-side power monitors from Analog Devices. It is functionally similar to other parts in the series but distinguished by its specific package type and temperature rating. The IDD suffix typically denotes the industrial grade version in a DFN package, differentiating it from MSOP variants or other temperature grades within the same functional family.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct substitutes like the LTC4151HMS#TRPBF if package differences are acceptable. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult Analog Devices documentation for detailed cross-reference information.
