LTC2913CDD-1#TRPBF

Supervisors Overview

The LTC2913CDD-1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring dual voltage rails. It operates within a supply voltage range of 1.7V to 5.5V and features adjustable under-voltage and over-voltage thresholds. The device draws a typical quiescent current of 55µA, ensuring efficient power management in battery-operated systems. It provides independent reset outputs for each monitored channel with configurable delay times. Packaged in an 8-pin DFN (3x2mm) surface-mount package, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision with independent threshold adjustment
• Configurable reset timing delays for precise system control
• Low quiescent current consumption for energy efficiency
• Compact 8-lead DFN package suitable for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Industrial control systems needing robust voltage supervision
• Telecommunications equipment with strict power integrity requirements
• Automotive infotainment systems utilizing low-power monitoring solutions

Supervisors Procurement Notes

Verify the exact suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the operating temperature range matches your specific application environment. Ensure compatibility with existing PCB footprints for the 8-DFN package. Check for any recent lifecycle notices or obsolescence warnings from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required without external comparators. Consider the adjustable threshold feature if standard fixed voltages do not meet design specifications. Evaluate the 55µA quiescent current against total system power budgets. Compare package dimensions against available board space constraints.

Supervisors Part Context

This part belongs to the LTC2913 family of dual-supervisory circuits. It shares functional similarities with other members like the LTC2912 but offers dual-channel capability instead of single-channel. The CDD suffix denotes the commercial temperature grade and DFN package type. It complements Analog Devices' broader portfolio of power management ICs focused on system reliability.

Supervisors Replacement Considerations

Direct substitutes include other LTC2913 variants with different package options such as LTC2913HMS8-1#TRMPBF for MSOP-8 packaging. Cross-reference with LTC2911 series if only single-channel monitoring is sufficient. Verify pinout compatibility before replacing with similar parts from other manufacturers.
