LTC2911CDDB-5

Supervisors Overview

The LTC2911CDDB-5#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc. It features three independent voltage monitors with a power-fail comparator, housed in an 8-lead DFN package (3mm x 2mm). The device operates within a temperature range of 0°C to 70°C and utilizes a push-pull or totem-pole output configuration. Key electrical parameters include a supply current of 10 µA, reset timeout of 140ms minimum, and monitored voltage thresholds of 4.425V, adjustable, and adjustable.

Supervisors Feature Summary

• Integrates three precise voltage monitoring channels for comprehensive power supervision.
• Includes a dedicated power-fail comparator for early warning detection.
• Features adjustable reset timeout capabilities for flexible system timing requirements.

Supervisors Applications

• Portable equipment requiring multi-voltage supervision
• Battery-powered systems needing low quiescent current
• Industrial control units with multiple power rails

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm availability status as distribution may vary. Ensure the operating temperature range meets your environmental requirements. Check RoHS compliance documentation for regulatory adherence. Validate pinout compatibility with your PCB layout design before finalizing procurement.

Supervisors Selection Notes

Select this component when three distinct voltage levels require simultaneous monitoring alongside a power-fail signal. The DFN-8 package suits space-constrained designs. Consider the 10 µA supply current for battery longevity. Verify that the adjustable thresholds align with your specific rail voltages. Ensure the 0°C to 70°C industrial temperature range fits your application environment.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. It shares core functionality with other variants like the ITS8 and IDDB packages but differs in case style and potentially threshold configurations. The CDDB-5 designation specifically identifies the commercial temperature grade and 8-lead DFN footprint.
