LTC4151IMS#PBF

Power Supply Controllers, Monitors Overview

The LTC4151IMS#PBF is a high-side current and power monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 7 V to 80 V and draws a typical operating supply current of 1.2 mA. The device supports I2C communication for monitoring current and voltage parameters. It is housed in a 10-lead MSOP package and is rated for an industrial temperature range from -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• High-side current sensing capability with integrated regulation functions
• I2C interface for digital communication and data retrieval
• Supports wide input voltage operation up to 80 V

Power Supply Controllers, Monitors Applications

• Current and power monitoring in industrial systems
• Voltage and current supervision in battery-powered devices
• Protection circuits requiring high-side sensing

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates a tube package, distinct from the #TRPBF tape-and-reel variant. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the component matches the required MSOP-10 footprint and lead-free specifications before integration into production designs.

Power Supply Controllers, Monitors Selection Notes

Select this component when high-side monitoring is required for voltages up to 80 V. The I2C interface simplifies system integration compared to analog output monitors. Consider the 1.2 mA supply current for low-power applications. Verify that the MSOP-10 package fits the PCB layout constraints and thermal requirements of the target environment.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC4151 family of current and power monitors. It shares functional similarities with other high-side sensors but is distinguished by its specific voltage range and I2C digital interface. The IMS designation confirms the industrial temperature grade and MSOP packaging.

Power Supply Controllers, Monitors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative high-side monitors from Analog Devices or other manufacturers based on voltage rating, interface type, and package compatibility.
