LTC2911IDDB-1

Supervisors Overview

The LTC2911IDDB-1 is a precision supervisory circuit manufactured by Analog Devices Inc. It features three independent voltage monitoring channels with power-fail comparison capabilities, housed in an 8-lead DFN package. The device operates with a low supply current of 10 µA and supports surface-mount installation. It provides adjustable reset timeout functionality and delivers active-low push-pull outputs for system reliability.

Supervisors Feature Summary

• Provides precise monitoring of multiple voltage rails with dedicated power-fail comparators
• Features adjustable reset timeout to accommodate specific system startup requirements
• Delivers active-low push-pull output signals for direct interface with logic circuits

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• System reset generation for embedded processors
• Voltage monitoring in portable battery-operated devices

Supervisors Procurement Notes

Verify the exact suffix and tape-and-reel packaging specifications against the manufacturer's datasheet before ordering. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required operating temperature range and pinout configuration for your specific PCB layout.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision with power-fail indication is required. Consider the 10 µA quiescent current for battery-sensitive designs. Verify that the adjustable timeout feature meets the system's startup timing constraints. Ensure the DFN-8 package fits within the available board space and thermal requirements.

Supervisors Part Context

This part belongs to the LTC2911 series of precision supervisory circuits from Analog Devices. The series offers various channel counts and package options to suit different monitoring needs. The IDDB-1 designation specifies the industrial temperature range and the specific DFN-8 footprint used in this configuration.

Supervisors Replacement Considerations

Check for compatible parts within the same family, such as the LTC2911ITS8-1#TRMPBF, which offers similar functionality in a TSOT-23-8 package. Verify pin compatibility and electrical parameters before substitution.
