LTC2908IDDB-A1#TRPBF

Supervisors Overview

The LTC2908IDDB-A1#TRPBF is a six-input power supply monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 5.5V and features an active-low/open-drain reset output with a fixed 200ms timeout. The device includes a manual reset input and utilizes an 8-lead DFN package measuring 3mm x 2mm with a height of 0.75mm. It supports monitoring up to six independent power rails, offering adjustable thresholds for specific inputs while maintaining precise supervision for critical system voltages.

Supervisors Feature Summary

• Provides simultaneous supervision for up to six independent power supply rails
• Features an active-low or open-drain reset output with a fixed 200ms timeout period
• Includes a manual reset input pin for external control capabilities
• Supports adjustable threshold voltages for flexible multi-supply monitoring applications

Supervisors Applications

• Systems requiring precise monitoring of multiple power supply voltages
• Compact multi-supply voltage supervision solutions
• Embedded systems with complex power distribution networks

Supervisors Procurement Notes

Verify the exact suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the 8-lead DFN EP package dimensions and thermal requirements. Cross-reference the specific A1 variant thresholds with design needs, as different suffixes denote distinct voltage configurations. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems that require centralized monitoring of multiple voltage rails within a compact footprint. The fixed 200ms timeout ensures reliable reset generation during power-up sequences. Consider the adjustable threshold options available in the A1 variant to match specific rail requirements. Evaluate the 8-lead DFN package for space-constrained PCB layouts and thermal management considerations.

Supervisors Part Context

The LTC2908 belongs to Analog Devices' family of multi-supply supervisors designed for complex embedded architectures. This series enables engineers to consolidate multiple voltage monitoring functions into a single integrated circuit. The IDDB-A1 variant specifically addresses applications needing flexible threshold configurations across its six monitored channels, providing a scalable solution for modern power management topologies.
