LTC2992IMS-1#PBF

Power Supply Controllers, Monitors Overview

The LTC2992IMS-1#PBF is a dual wide-range power monitor manufactured by Analog Devices Inc. It measures current, voltage, and power for two independent supplies within a 0V to 100V range, independent of the input supply voltage. The device operates on a 2.7V to 100V supply and includes an integrated shunt regulator for monitoring sources exceeding 100V. It features an I2C interface with a maximum clock frequency of 600kHz and supports high-side or low-side sensing configurations. Packaged in a 16-pin MSOP, it functions as a rail-to-rail system monitor suitable for automotive and industrial applications.

Power Supply Controllers, Monitors Feature Summary

• Measures current, voltage, and power for two independent power supplies simultaneously
• Provides a 0V to 100V measurement range that remains independent of the input supply voltage
• Integrates a shunt regulator specifically designed for monitoring power supplies exceeding 100V
• Supports both high-side and low-side current sensing configurations via I2C interface

Power Supply Controllers, Monitors Applications

• -48V redundant feed systems with transient protection up to 200V
• Bidirectional high-side power monitoring for voltages between 30V and 300V
• Dual bipolar power supply monitoring with negative voltage supervision

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package integrity and pin alignment against the official 16-pin MSOP specification. Ensure the suffix matches the required tape-and-reel or tube configuration for your assembly process. Check RoHS compliance status prior to integration into final products.

Power Supply Controllers, Monitors Selection Notes

Select this component when simultaneous dual-supply monitoring is required across a wide voltage spectrum. It is appropriate for designs needing precise power calculations without external microcontrollers. Consider the 16-pin MSOP footprint for space-constrained layouts. Verify that the I2C bus speed requirements align with the 600kHz maximum limit specified in the datasheet.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2992 family of dual wide-range power monitors. It shares core functionality with variants like the LTC2992CMS-1#PBF and LTC2992HMS-1#PBF, differing primarily in package type and temperature rating. The IMS-1 variant specifically utilizes the MSOP package format for surface-mount applications requiring compact board real estate.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include other members of the LTC2992 series such as the LTC2992CMS-1#PBF or LTC2992HMS-1#PBF, provided the package and temperature specifications match the design requirements. Cross-reference with the manufacturer's selection guide for compatible alternatives.
