LTC2922IF-2.5#PBF

Power Supply Controllers, Monitors Overview

The LTC2922IF-2.5#PBF is a power supply tracker and monitor manufactured by Analog Devices Inc., housed in a TSSOP-20 surface-mount package. It operates within a supply voltage range of 2.7 V to 100 V, with a typical quiescent current of 2 mA. The device supports an operating temperature range from -40°C to +85°C. It integrates input monitoring capabilities for tracking multiple power rails, featuring adjustable thresholds and open-drain outputs to ensure precise sequencing and supervision in complex multi-supply systems.

Power Supply Controllers, Monitors Feature Summary

• Integrates power supply tracking logic with simultaneous input voltage monitoring for coordinated rail sequencing.
• Supports wide input voltage ranges up to 100 V, enabling compatibility with high-voltage industrial and telecom bus architectures.
• Provides configurable output signals via open-drain pins to interface directly with system controllers or microprocessors.

Power Supply Controllers, Monitors Applications

• Multi-rail power sequencing in telecommunications infrastructure equipment
• Voltage supervision and tracking in industrial control systems
• Power management in server and networking hardware requiring precise startup sequences

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'IF-2.5' against official Analog Devices documentation to confirm threshold settings and package variant. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Ensure the selected component matches the required thermal and electrical specifications for the target application environment before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing systems that require integrated tracking and monitoring functions without external logic. Consider the 2 mA quiescent current and TSSOP-20 footprint during PCB layout. Verify that the input voltage range and operating temperature limits align with the system's worst-case conditions. Compare against simpler supervisors if tracking functionality is not required to optimize cost and complexity.

Power Supply Controllers, Monitors Part Context

The LTC2922 belongs to Analog Devices' family of power supply trackers and monitors. This series is designed to manage the startup and shutdown sequences of multiple power rails, ensuring that voltages rise and fall in the correct order. The IF-2.5 variant specifically denotes the package type and internal reference or threshold configuration, distinguishing it from other pin-compatible or functionally similar parts in the LTC2922 lineup.

Power Supply Controllers, Monitors Replacement Considerations

Consult Analog Devices datasheets for direct pin-to-pin replacements within the LTC2922 series. Verify functional equivalence regarding tracking logic and monitoring channels. No public substitute part numbers are confirmed in the provided source material; generic cross-references should be validated against official manufacturer guidelines.
