LTC2914IGN-2#TRPBF

Supervisors Overview

The LTC2914IGN-2#TRPBF is a quad input voltage monitor from Analog Devices, designed to supervise multiple power rails in complex systems. It features adjustable under-voltage and over-voltage thresholds with a guaranteed accuracy of ±1.5% across the operating temperature range. The device supports monitoring up to two negative voltages and includes an open-drain reset output with an 8.5 ms delay. Operating on a single supply up to 7 V, it draws only 70 µA. Packaged in a 16-lead SSOP for surface mount installation.

Supervisors Feature Summary

• Simultaneously monitors four independent voltage inputs
• Adjustable UV/OV trip points with high precision
• Capable of supervising dual negative voltage rails
• Includes buffered 1V reference output

Supervisors Applications

• Multi-rail server power distribution units
• Industrial control system power supervision
• Telecommunications equipment voltage monitoring
• Portable electronic device battery management

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the SSOP package variant matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's maximum supply limits. Check RoHS compliance documentation for regulatory adherence. Validate that the open-drain output configuration suits your logic interface.

Supervisors Selection Notes

Select this component when precise multi-voltage supervision is required without manual reset functionality. Consider the low quiescent current for battery-sensitive applications. The adjustable thresholds allow customization for specific rail tolerances. Verify compatibility with negative voltage inputs if applicable. Ensure the thermal performance meets your enclosure constraints.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits. It shares core monitoring capabilities with variants like the LTC2914IGN-2#PBF but differs in packaging format. The series is designed for general-purpose voltage monitoring in portable and industrial electronics. It complements other PMIC solutions by providing dedicated fault detection.

Supervisors Replacement Considerations

LTC2914IGN-2#PBF offers identical electrical specifications in tube packaging. LTC2914HDHC-2#PBF provides the same functionality in a DFN-16 package. Verify pinout compatibility before substituting different package types. Ensure threshold settings remain within acceptable ranges for the new variant.
