LTC2951ITS8-2#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2951ITS8-2#TRPBF is a dual-channel, high-side current sense amplifier manufactured by Analog Devices Inc. It features an integrated precision reference and low drift amplifiers designed for accurate current monitoring in industrial and automotive applications. The device operates with a supply voltage range of 2.7V to 5.5V and supports input common-mode voltages up to 60V. It offers a fixed gain of 20V/V and includes an enable pin for power management. The component is housed in an 8-lead MSOP package and is rated for operation over an extended temperature range.

Power Supply Controllers, Monitors Feature Summary

• Dual-channel architecture providing independent current sensing capabilities within a single compact package
• Integrated precision voltage reference eliminates the need for external reference components
• High common-mode voltage tolerance allows direct connection to high-side loads without level shifting
• Low offset voltage and drift ensure high accuracy across wide operating temperature ranges

Power Supply Controllers, Monitors Applications

• Industrial motor control systems requiring precise phase current monitoring
• Automotive battery management systems for cell balancing and state estimation
• Power distribution units needing redundant current protection channels
• Battery charger circuits for charge current regulation and fault detection

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'ITS8-2' matches the required gain and package configuration. Confirm the '#TRPBF' designation indicates tape-and-reel packaging with lead-free compliance. Ensure the manufacturer source is authorized to guarantee authenticity and traceability. Check for any recent obsolescence notices or lifecycle status updates from Analog Devices before finalizing procurement plans.

Power Supply Controllers, Monitors Selection Notes

Select this component when dual-channel high-side sensing is required with minimal external component count. The fixed 20V/V gain suits applications where output voltage swing aligns with standard ADC input ranges. Consider the 60V common-mode limit against system rail voltages. Evaluate thermal performance in the MSOP package if high continuous currents are monitored. Compare against single-channel alternatives if only one sensing path is necessary to reduce cost.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC295x family of current sense amplifiers, which integrate references and amplifiers for simplified design. The ITS8-2 variant specifically denotes the 8-lead MSOP package with a fixed gain setting. It complements other devices in the series that may offer adjustable gains or different package options for space-constrained designs.

Power Supply Controllers, Monitors Replacement Considerations

Direct replacements include other LTC295x variants with compatible gain and package types. Verify pinout compatibility before substituting with similar parts from Analog Devices or competitors. Ensure replacement devices support the same 60V common-mode voltage and supply range requirements.
