LTC2904CDDB#TRMPBF

Supervisors Overview

The LTC2904CDDB#TRMPBF is a dual-channel supervisory circuit manufactured by Analog Devices Inc. It features precision voltage monitoring with pin-selectable thresholds, allowing for flexible configuration without external resistors. The device operates within a supply voltage range of 1.7V to 5.5V and provides open-drain or open-collector reset outputs. Packaged in an 8-DFN (3x2) surface-mount case, it supports industrial temperature ranges and includes features such as adjustable reset timeouts and manual reset capability.

Supervisors Feature Summary

• Dual-channel supervision with independent threshold selection via dedicated pins
• Configurable reset output timing and polarity options
• Manual reset input functionality for system control

Supervisors Applications

• Multi-voltage rail monitoring in embedded systems
• Industrial control board power supervision
• Communication equipment voltage integrity checks

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging with moisture sensitivity level 1. Confirm the 'C' grade designation matches required operating temperature specifications. Ensure the 8-DFN footprint aligns with PCB design constraints. Cross-reference datasheet revision dates for any recent parameter updates before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise, resistor-free threshold setting is required for multiple voltage rails. Compare against single-channel supervisors if only one rail needs monitoring. Consider the open-drain output compatibility with downstream logic levels. Evaluate thermal performance requirements against the DFN package's heat dissipation characteristics for dense layouts.

Supervisors Part Context

This part belongs to the LTC2904/2905 family of supervisory circuits. It shares functional similarities with the LTC2905 but differs in specific threshold configurations and feature sets. Both devices utilize the same 8-DFN package and offer pin-selectable thresholds, simplifying bill-of-materials management across different product variants within the same platform.

Supervisors Replacement Considerations

The LTC2905CDDB#TRMPBF is a related variant within the same family. Verify pinout compatibility and threshold availability before substitution. Ensure the replacement meets the same voltage range and temperature specifications.
