LTC2914CDHC-2#TRPBF

Supervisors Overview

The LTC2914CDHC-2#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple power 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 a reset delay time of 8.5 ms and functions reliably across a temperature range from -40°C to +125°C, 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
• Features adjustable threshold voltages for flexible application design

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 CDHC grade corresponds to the commercial temperature range requirements of your design. Ensure the DFN-16 package dimensions align with your PCB footprint constraints. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to final procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required without external comparators. The adjustable thresholds allow customization for various logic levels. Consider the 70 µA quiescent current impact on overall system efficiency. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Supervisors Part Context

This part belongs to the LTC2914 series of multi-channel voltage supervisors. It shares functional similarities with other members like the LTC2912 but offers higher channel density. The DFN-16 package provides a compact solution for space-constrained designs. It serves as a critical reliability component in complex power architectures requiring comprehensive fault detection.

Supervisors Replacement Considerations

Direct substitutes include other LTC2914 variants with different package options or temperature grades. Verify compatibility with existing firmware if software-based monitoring is utilized. Ensure replacement parts maintain the same open-drain output characteristics and reset delay specifications.
