LTC2919CDDB-5#TRPBF

Supervisors Overview

The LTC2919CDDB-5#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It features an open-drain output and operates within a supply voltage range up to 6 V. The device monitors three inputs with a fixed threshold of 4.425 V for the primary channel, while allowing adjustable thresholds for others. It provides a reset timeout of at least 140 ms and maintains accuracy within 1.5%. Operating temperatures span from 0°C to +70°C, with a typical quiescent current of 50 µA.

Supervisors Feature Summary

• Monitors multiple input voltages including under-voltage, over-voltage, and negative voltage conditions
• Provides precise threshold detection with low power consumption characteristics
• Features open-drain reset output compatible with various logic families

Supervisors Applications

• Portable equipment battery monitoring
• Industrial control system power supervision
• Communication infrastructure voltage tracking

Supervisors Procurement Notes

Verify the exact suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range meets specific environmental requirements for the target application environment.

Supervisors Selection Notes

Select this component when precise multi-channel voltage supervision is required in space-constrained designs. The DFN package offers a compact footprint suitable for dense PCB layouts. Consider the fixed versus adjustable threshold options based on specific circuit requirements and ensure compatibility with the system's logic levels.

Supervisors Part Context

This part belongs to the LTC2919 series of precision voltage monitors. It shares functional similarities with other members like the LTC2919CMS-5#PBF but differs in package type and packaging format. The series is designed for applications requiring accurate voltage supervision with minimal power impact.

Supervisors Replacement Considerations

LTC2919CDDB-5#TRMPBF is a verified equivalent variant differing only in packaging format.
