LTC2914CDHC-1#TRPBF

Supervisors Overview

The LTC2914CDHC-1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent channels capable of detecting both under-voltage and over-voltage conditions on positive and negative supplies. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 70µA. It utilizes a DFN-16 package and supports tape-and-reel packaging for automated assembly.

Supervisors Feature Summary

• Provides simultaneous monitoring of up to four distinct voltage inputs
• Detects both under-voltage and over-voltage events across positive and negative rails
• Integrates an open-drain reset output with configurable delay times

Supervisors Applications

• Multi-rail power system supervision in industrial equipment
• Voltage monitoring for embedded computing platforms
• Power integrity verification in telecommunications infrastructure

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging configuration. Confirm the CDHC variant meets commercial temperature specifications. Ensure compatibility with existing board layouts requiring DFN-16 footprints. Validate that the four-channel architecture aligns with the target design's monitoring requirements before procurement.

Supervisors Selection Notes

Select this component when comprehensive multi-rail supervision is required within a compact footprint. The four-channel capability reduces bill-of-materials complexity compared to discrete solutions. Consider the 70µA quiescent current for battery-sensitive applications. Verify that the DFN-16 package dimensions fit the mechanical constraints of the enclosure.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It complements other members like the LTC2911 and LTC2912, which offer fewer channels or different pin configurations. The series provides scalable monitoring solutions for complex power architectures without requiring external logic components.

Supervisors Replacement Considerations

Direct substitutes include the LTC2914HDHC-1#PBF for tube packaging or the LTC2914IDHC-1#TRPBF for extended temperature ranges. Verify pinout compatibility and threshold settings when cross-referencing with similar multi-channel monitors.
