LTC2908IDDB-C1#TRPBF

Supervisors Overview

The LTC2908IDDB-C1#TRPBF is a six-input power supply monitor from Analog Devices, housed in an 8-lead DFN package. It provides precise supervision for multiple voltage rails, including fixed thresholds such as 2.338V and adjustable inputs. The device features active-low or open-drain outputs to signal under-voltage conditions. Designed for compact systems requiring multi-supply monitoring, it operates with a low quiescent current of 50 µA. The component supports surface-mount installation and is suitable for applications demanding accurate voltage tracking across various digital logic levels.

Supervisors Feature Summary

• Provides simultaneous monitoring of up to six independent power supply voltages within a single compact package.
• Delivers precise under-voltage detection with both fixed threshold options and fully adjustable input channels.
• Generates system reset signals via active-low or open-drain output pins to ensure processor safety during fault conditions.

Supervisors Applications

• Multi-rail power distribution units requiring centralized voltage supervision
• Embedded systems monitoring mixed voltage domains such as 12V, 5V, and logic levels
• Industrial control boards supervising analog and digital power rails

Supervisors Procurement Notes

Verify the complete part number including the suffix #TRPBF to confirm tape-and-reel packaging configuration. Ensure compatibility with the specific voltage thresholds required by your design, as the C1 variant offers distinct fixed and adjustable channel combinations compared to other LTC2908 derivatives. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Supervisors Selection Notes

Select this component when designing systems that require monitoring more than four supply rails without consuming excessive board space. Consider the trade-off between fixed threshold precision and the flexibility of adjustable inputs. Evaluate the total quiescent current impact on battery life if used in portable applications. Compare against simpler single-channel supervisors if only one rail requires protection to optimize cost and complexity.

Supervisors Part Context

This part belongs to the LTC2908 family of multi-supply monitors, designed for applications needing comprehensive power integrity management. Unlike single-channel supervisors, it consolidates multiple monitoring functions into one IC. The IDDB-C1 designation specifies the industrial temperature range and specific pinout configuration. It complements other PMIC components by handling critical reset generation tasks independently.

Supervisors Replacement Considerations

Direct substitutes include other LTC2908 variants such as LTC2908IDDB-A1 or LTC2908CDDB-B1, which offer different fixed threshold combinations. Verify that the replacement matches the required number of adjustable versus fixed channels. Ensure the package footprint remains compatible with existing PCB layouts when swapping between these family members.
