LTC2908CDDB-A1#TRMPBF

Supervisors Overview

The LTC2908CDDB-A1#TRMPBF is a six-input power supply monitor manufactured by Analog Devices Inc. It operates within a voltage range of 2.7V to 5.5V and features an active-low open-drain reset output. The device provides precise monitoring for multiple rails, including fixed thresholds at 4.675V, 3.086V, 2.338V, and 1.683V, alongside two adjustable inputs. It utilizes an 8-pin DFN package with an exposed pad for thermal management.

Supervisors Feature Summary

• Supports simultaneous monitoring of up to six independent power supply rails
• Provides precise voltage supervision with both fixed and configurable threshold options
• Features an active-low open-drain reset signal for system integration

Supervisors Applications

• Multi-rail power distribution systems in industrial equipment
• Embedded computing platforms requiring sequential power-up/down sequencing
• Telecommunications infrastructure monitoring solutions

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with your PCB footprint, as the DFN-8 package requires careful thermal design. Cross-reference the exact part number with authorized distributors to avoid counterfeit components, as availability may vary by region.

Supervisors Selection Notes

Select this component when designing systems that require centralized supervision of multiple voltage domains without external comparators. The inclusion of adjustable inputs allows flexibility for non-standard rail voltages. Consider the 8-pin DFN form factor for space-constrained layouts. Verify that the required reset timing and hysteresis characteristics meet the target processor or FPGA specifications.

Supervisors Part Context

This part belongs to the LTC2908 family of multi-supply supervisors. It shares functional similarities with the LTC2905 and LTC2904 but offers expanded capacity for six inputs. The CDDB variant indicates commercial temperature range operation. It serves as a compact alternative to discrete comparator-based monitoring circuits in modern portable and industrial electronics.

Supervisors Replacement Considerations

Direct substitutes include other members of the LTC2908 series with different threshold configurations, such as LTC2908IDDB-A1. For fewer channels, the LTC2905CDDB may be considered if only two rails require monitoring. Always verify pinout compatibility and electrical specifications before substitution.
