LTC2908CDDB-A1#TRPBF

Supervisors Overview

The LTC2908CDDB-A1#TRPBF is a precision six-input supply monitor manufactured by Analog Devices Inc. It operates within an input voltage range of 0.5V to 36V and features a quiescent current of 50µA. The device provides active-low open-drain outputs for each channel, with selectable thresholds including fixed values such as 4.675V, 3.086V, 2.338V, and 1.683V, alongside two adjustable inputs. It is housed in an 8-pin DFN package and supports industrial temperature ranges.

Supervisors Feature Summary

• Six independent voltage monitoring channels with precise threshold detection
• Active-low open-drain output configuration for flexible logic interfacing
• Combination of fixed and fully adjustable input thresholds
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Monitoring multiple power rails in embedded processor systems
• Industrial control unit power supervision
• Telecommunications infrastructure voltage tracking
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix A1 against the official Analog Devices datasheet to confirm the exact threshold configuration matches the design requirements. Confirm the DFN-8 package availability and ensure the operating temperature range aligns with the environmental conditions of the target application before finalizing procurement.

Supervisors Selection Notes

Select this component when a system requires simultaneous monitoring of up to six distinct voltage sources within a compact footprint. The inclusion of adjustable inputs allows customization for non-standard rail voltages, while fixed thresholds simplify design for common logic levels. Ensure the total number of monitored rails does not exceed the six-channel capacity.

Supervisors Part Context

This part belongs to the LTC2908 family of precision supply monitors designed for applications requiring accurate voltage supervision. It serves as a critical component in ensuring system reliability by detecting under-voltage or over-voltage conditions across multiple power domains simultaneously.

Supervisors Replacement Considerations

Consult the Analog Devices product selector guide for alternative parts within the LTC2908 series that may offer different threshold configurations or package options. Verify pin compatibility and electrical specifications before substituting with other supervisory circuits.
