LTC2908IDDB-A1#TRMPBF

Supervisors Overview

The LTC2908IDDB-A1#TRMPBF is a six-input power supply monitor manufactured by Analog Devices Inc. It operates within an 1.7V to 5.5V supply range and features a quiescent current of 50µA. The device provides active-low open-drain outputs for fault indication and includes a manual reset output with a selectable delay. It is housed in an 8-lead DFN package.

Supervisors Feature Summary

• Monitors up to six independent voltage rails simultaneously
• Provides precise threshold detection for critical power lines
• Features configurable reset timing and manual control inputs

Supervisors Applications

• Multi-rail server and storage system power supervision
• Industrial equipment requiring comprehensive voltage monitoring
• Telecommunications infrastructure power management

Supervisors Procurement Notes

Verify the specific suffix A1 against the target design requirements, as it defines fixed voltage thresholds distinct from other variants. Confirm the TRMPBF designation indicates tape-and-reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with the required operating temperature range and package dimensions before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a system requires simultaneous monitoring of multiple voltage rails without external comparator circuitry. The fixed threshold configuration simplifies design compared to adjustable variants. Consider the DFN package size for space-constrained layouts and verify that the open-drain output structure aligns with the downstream logic voltage levels.

Supervisors Part Context

This part belongs to the LTC2908 family of multi-supply monitors designed for complex power architectures. It serves as a compact alternative to discrete supervisory circuits, integrating multiple comparators and timers into a single solution. The family supports various threshold combinations to accommodate different industry-standard voltage rails.

Supervisors FAQ

What is the function of the RESET pin?

The RESET pin provides an active-low open-drain signal indicating that one or more monitored supplies have fallen below their respective thresholds.

How is the reset delay configured?

The reset delay time is determined by an external capacitor connected to the DELAY pin, allowing for customizable debounce periods.
