LTC2917IDDB-B1#TRPBF

Supervisors Overview

The LTC2917IDDB-B1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and features a low quiescent current of 30 µA. The device is housed in a compact MSOP-10 surface-mount package, designed for efficient space utilization in dense electronic assemblies.

Supervisors Feature Summary

• Integrates 27 selectable voltage thresholds for precise monitoring
• Includes a built-in watchdog timer with timeout functionality
• Supports simultaneous under-voltage and over-voltage detection

Supervisors Applications

• Industrial control system power supervision
• Embedded processor board voltage monitoring
• Telecommunications equipment protection circuits

Supervisors Procurement Notes

Verify the specific suffix B1 against official Analog Devices documentation to confirm threshold configurations. Ensure the MSOP-10 package dimensions match the target PCB footprint. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Supervisors Selection Notes

Select this component when multiple independent voltage rails require monitoring within a single IC. The integrated watchdog feature reduces external component count compared to discrete solutions. Evaluate the 30 µA quiescent current against system power budget constraints for battery-operated applications.

Supervisors Part Context

This part belongs to the LTC2917 series of supervisory circuits. It shares functional similarities with other models in the family but differs in package type and specific threshold settings. The IDDB designation indicates the industrial temperature grade and DFN/MSOP packaging style.

Supervisors Replacement Considerations

LTC2917IDDB-A1#TRMPBF serves as a potential alternative within the same series. Verify that the A1 variant's threshold configuration matches the design requirements before substitution.
