LTC2908CDDB-C1#TRMPBF

Supervisors Overview

The LTC2908CDDB-C1#TRMPBF is a six-input supply monitor from Analog Devices, designed for systems requiring precise and compact monitoring of multiple power rails. It operates within an industrial temperature range and features a DFN-8 package. The device monitors voltages such as 12V, 5V, 3.3V, 2.5V, 1.8V, and 1.5V. It includes a watchdog timer with a timeout period of 140ms minimum and offers open-drain or open-collector reset outputs. The component draws a typical quiescent current of 50 µA.

Supervisors Feature Summary

• Provides simultaneous supervision for up to six independent voltage inputs
• Integrates a programmable watchdog timer for system reliability
• Delivers active-low reset signals via open-drain or open-collector outputs

Supervisors Applications

• Multi-rail power distribution units in embedded systems
• Industrial control boards requiring comprehensive voltage oversight
• Telecommunications equipment monitoring critical logic and analog supplies

Supervisors Procurement Notes

Verify the exact suffix C1 against the manufacturer's datasheet to confirm threshold configurations. Ensure the DFN-8 footprint matches your PCB layout constraints. Confirm availability status as supply may be limited. Cross-reference the specific part number with official distributor catalogs to validate authenticity and lot traceability before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing circuits that require monitoring more than four voltage rails simultaneously. It is suitable for applications needing low quiescent current consumption to preserve battery life. Consider the DFN-8 package size if board space is constrained. Verify that the monitored voltage levels fall within the operational input range specified in the electrical characteristics table.

Supervisors Part Context

This part belongs to the LTC2908 series of multi-supply supervisors. It shares functional similarities with other members like the LTC2908IDDB-C1 but differs in temperature grade and packaging options. The series is designed to replace discrete comparator solutions, offering higher accuracy and reduced component count in complex power management architectures.

Supervisors Replacement Considerations

Direct substitutes include other variants within the LTC2908 family, such as the LTC2908IDDB-C1#TRPBF, provided the temperature rating and pinout compatibility are verified. Check datasheets for equivalent threshold settings and output drive capabilities before swapping components.
