LTC2911HDDB-1#TRPBF

Supervisors Overview

The LTC2911HDDB-1#TRPBF is a precision triple power supply monitor manufactured by Analog Devices Inc. It monitors three independent voltage inputs simultaneously within a compact DFN-8 package. The device features an ultralow voltage reset capability, ensuring reliable operation down to VCC = 0.5V. It integrates a power-fail comparator for system status indication and operates across a wide temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors three independent voltage inputs simultaneously
• Provides ultralow voltage reset functionality down to 0.5V
• Integrates a dedicated power-fail comparator

Supervisors Applications

• Portable instrumentation systems requiring multiple voltage rails monitoring
• Industrial automation equipment with strict supervisory requirements
• Embedded systems needing simultaneous multi-supervision

Supervisors Procurement Notes

Verify the specific suffix HDDB-1 against official Analog Devices documentation to confirm pinout and threshold configurations. Ensure compatibility with existing PCB footprints and thermal management strategies. Confirm availability through authorized distributors as supply conditions may vary.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required in space-constrained designs. The integrated power-fail comparator eliminates the need for external logic gates. Consider the DFN-8 package size and operating temperature range relative to the target application environment.

Supervisors Part Context

This part belongs to the LTC2911 series of precision power supply monitors from Analog Devices. The series offers various channel counts and package options to suit different design complexities. The HDDB-1 variant specifically targets applications requiring triple supervision in a small footprint.

Supervisors Replacement Considerations

Consult Analog Devices official cross-reference lists for verified substitutes. Generic equivalents may not match the precise threshold tolerances or ultralow voltage reset characteristics.
