LTC2916IDDB-1#TRPBF

Supervisors Overview

The LTC2916IDDB-1#TRPBF is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It features nine selectable threshold voltages and provides an open-drain reset output with a fixed 200 ms reset delay time. The device operates within a supply voltage range of up to 5.5 V and maintains an accuracy of 1.5%. It functions reliably across an extended industrial temperature range from -40°C to +125°C, drawing a typical quiescent current of 30 µA. The component is housed in an 8-pin DFN package.

Supervisors Feature Summary

• Provides manual reset functionality with configurable threshold selection
• Features low quiescent current consumption for power-sensitive applications
• Delivers precise voltage monitoring with high accuracy specifications

Supervisors Applications

• Portable instrumentation systems requiring reliable power supervision
• Industrial automation equipment needing extended temperature operation
• Embedded controllers utilizing single-supply architectures

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging configuration. Confirm the IDDB variant meets industrial temperature requirements compared to CDDB commercial grades. Ensure compatibility with existing PCB footprints for the DFN-8 package. Cross-reference datasheet revisions for any pinout or electrical characteristic updates prior to final procurement decisions.

Supervisors Selection Notes

Select this component when nine distinct threshold options are required for a single monitored rail. Consider the 200 ms fixed delay against application timing constraints. Evaluate the 1.5% accuracy specification against system tolerance requirements. Compare the 30 µA quiescent current against battery life expectations in portable designs.

Supervisors Part Context

This part belongs to the LTC2916 series of voltage supervisors from Analog Devices. It shares architectural similarities with the LTC2915 but offers different threshold configurations. The DFN-8 package allows for compact surface-mount integration. The series supports various operating temperatures depending on the specific grade suffix.

Supervisors Replacement Considerations

LTC2916CDDB-1#TRPBF serves as a commercial-grade alternative with identical electrical characteristics but limited to 0°C to 70°C operation. Verify thermal requirements before substitution.
