LTC2914IDHC-2#TRPBF

Supervisors Overview

The LTC2914IDHC-2#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent inputs capable of detecting both under-voltage and over-voltage conditions. The device utilizes an open-drain output configuration to signal fault states. It operates within a supply voltage range up to 7 V and maintains an accuracy of 1.5%. The component supports adjustable threshold voltages and includes a reset delay time of 8.5 ms. It functions reliably across an extended temperature range from -40°C to +125°C while consuming 70 µA of operating current.

Supervisors Feature Summary

• Monitors four independent voltage inputs for under-voltage and over-voltage faults
• Provides open-drain output signaling for fault detection
• Supports adjustable threshold voltage settings for flexible application requirements

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the ID variant meets the required industrial temperature specifications compared to other grade options. Ensure compatibility with the target board's DFN-16 footprint and soldering profile. Cross-reference the exact part number with official Analog Devices documentation to confirm pinout and electrical characteristics match the design intent.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required without external comparator complexity. The adjustable thresholds allow customization for various logic levels and power domains. Consider the 70 µA quiescent current impact on overall system efficiency. Verify that the open-drain output interface aligns with the downstream microcontroller or FPGA input requirements.

Supervisors Part Context

This part belongs to the LTC2914 series of multi-channel voltage supervisors. It shares architectural similarities with the LTC2910 but offers fewer channels optimized for compact designs. The DFN-16 package provides a small form factor suitable for space-constrained printed circuit boards. It serves as a dedicated solution for power management integrity in complex electronic systems.
