LTC2911IDDB-5#TRPBF

Supervisors Overview

The LTC2911IDDB-5#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc. It features three independent voltage monitor channels designed to track system power rails. The device provides under-voltage and over-voltage detection capabilities with an adjustable threshold for one channel, while the other two utilize fixed thresholds. It operates within a supply voltage range of 1.7V to 6V and includes a manual reset input. The component supports push-pull or open-drain output configurations and offers selectable reset delay times to ensure stable system operation during transient events.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct voltage inputs for comprehensive power rail supervision
• Features configurable output drivers allowing selection between push-pull and open-drain logic states
• Includes a manual reset pin that allows external assertion of the reset signal independent of voltage conditions
• Offers selectable reset delay timers to accommodate specific startup sequencing requirements

Supervisors Applications

• Multi-rail embedded system power management
• Industrial control board supervision
• Telecommunications equipment voltage monitoring
• Portable electronic device power integrity verification

Supervisors Procurement Notes

Verify the exact suffix designation against official Analog Devices documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required output configuration and threshold specifications. Cross-reference the manufacturer datasheet for any recent product change notifications or lifecycle status updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when precise monitoring of multiple voltage lines is required in space-constrained designs. Evaluate the fixed versus adjustable threshold options to match specific system voltage tolerances. Consider the operating temperature range and supply voltage limits to ensure compatibility with the target application environment and power architecture.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. The series is characterized by high accuracy and low power consumption, suitable for battery-operated and portable applications. The IDDB-5 variant specifically denotes the industrial temperature range and the DFN-8 package configuration, distinguishing it from other thermal or packaging variants within the same functional family.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the specific threshold accuracies or output drive characteristics. Verify pinout compatibility and electrical parameters before considering any cross-references.
