LTC2917IDDB-A1#TRPBF

Supervisors Overview

The LTC2917IDDB-A1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages. It operates within the LTC2917 series and utilizes an 8-lead DFN surface-mount package. The device functions as a voltage monitor with specific threshold configurations defined by its suffix. It is classified under PMIC supervisory circuits and supports SMD/SMT installation methods for integration into compact electronic designs.

Supervisors Feature Summary

• Provides continuous monitoring of system power rails to detect out-of-range conditions
• Integrates a comparator output for asserting reset or alarm signals when thresholds are breached
• Utilizes a low-profile DFN-8 package suitable for space-constrained printed circuit board layouts

Supervisors Applications

• Portable instrumentation systems requiring reliable power supervision
• Industrial automation equipment needing robust voltage monitoring
• Embedded control units utilizing single-supply operation

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific A1 suffix configuration matches design requirements, as it defines internal threshold parameters. Check current availability status as supply may be limited. Ensure storage and handling procedures comply with moisture sensitivity levels specified in the official datasheet to maintain device integrity during assembly.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with fixed threshold characteristics is required. The A1 variant offers specific trip points distinct from other suffixes in the LTC2917 family. Consider the DFN-8 footprint for PCB layout constraints. Evaluate quiescent current consumption against system battery life requirements. Compare performance against alternative supervisors if adjustable thresholds or additional channels are needed.

Supervisors Part Context

This part belongs to the LTC2917 series of supervisory circuits from Analog Devices. The series includes variants with different threshold configurations and package options. The IDDB designation indicates industrial temperature range operation and the DFN-8 package style. Related parts include the LTC2911 and LTC2912, which offer similar monitoring functionalities with varying channel counts and features.

Supervisors Replacement Considerations

Direct substitutes within the same series include the LTC2917IDDB-A2#TRPBF and LTC2917IDDB-A3#TRPBF, which share the same package but feature different voltage threshold settings. Verify that the electrical characteristics of the replacement match the original design specifications before implementation.
