LTC2906IDDB#TRMPBF

Supervisors Overview

The LTC2906IDDB#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., housed in an 8-DFN package. It functions as a dual-channel voltage monitor with one pin-selectable threshold. The device operates within a supply voltage range of 1.25 V to 5.5 V and supports a maximum input voltage of 5.5 V. It features adjustable reset timeout periods and provides open-drain or open-collector outputs for low-active reset signals. The component is designed for surface-mount installation and complies with RoHS standards.

Supervisors Feature Summary

• Dual-channel supervision with one pin-selectable threshold
• Adjustable reset timeout functionality
• Open-drain/open-collector output configuration

Supervisors Applications

• Portable instrumentation
• Industrial automation systems
• Embedded controller monitoring

Supervisors Procurement Notes

Verify current availability status directly with authorized distributors, as supply constraints may apply. Confirm the specific suffix matches the required pin-selectable threshold configuration. Ensure the 8-DFN footprint aligns with the target PCB design. Validate that the operating temperature range meets environmental requirements. Cross-reference datasheet revisions to ensure compatibility with existing system designs.

Supervisors Selection Notes

Select this component when dual-voltage monitoring is required with minimal external components. The pin-selectable threshold feature simplifies bill-of-materials management compared to fixed-threshold alternatives. Consider the 8-DFN package size for space-constrained layouts. Verify that the 5.5 V maximum rating covers all monitored rails. Evaluate the adjustable timeout against system startup timing requirements.

Supervisors Part Context

This part belongs to the LTC2906 series of precision supervisors from Analog Devices. It shares the DFN-8 form factor with related models like the LTC2909 but differs in channel count and threshold configuration. The IDDB suffix indicates the industrial temperature grade and specific package variant. It serves as a compact solution for multi-rail power integrity verification.
