LTC2905CDDB#TRPBF

Supervisors Overview

The LTC2905CDDB#TRPBF is a dual-channel supervisory circuit manufactured by Analog Devices Inc. in an 8-lead DFN package. It monitors two independent voltage inputs and generates active-low reset signals when thresholds are exceeded. The device features an adjustable reset timeout of 140ms minimum, open-drain outputs, and operates within a temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with configurable threshold combinations
• Active-low reset output with programmable timeout delay
• Open-drain output structure for flexible logic interfacing

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as #TRMPBF indicates tape-and-reel packaging while #TRPBF may denote tube or alternative reel specifications. Confirm RoHS compliance status and lead-free soldering compatibility prior to integration into production assemblies.

Supervisors Selection Notes

Select this component when dual-voltage supervision is required in space-constrained designs. Ensure the available threshold combinations cover the target supply rails. Verify that the open-drain output architecture aligns with the downstream logic requirements.

Supervisors Part Context

This part belongs to the LTC2905 series of multi-supervisor ICs designed for compact power management applications. It provides reliable system protection by detecting under-voltage conditions across multiple rails simultaneously.

Supervisors Replacement Considerations

LTC2905CDDB#TRMPBF is a confirmed substitute offering identical electrical characteristics with tape-and-reel packaging.
