LTC2913HDD-2#TRPBF

Supervisors Overview

The LTC2913HDD-2#TRPBF is a dual-channel supervisory circuit manufactured by Analog Devices Inc. It monitors two independent voltage rails for under-voltage and over-voltage conditions. The device features adjustable UV and OV trip points with a guaranteed threshold accuracy of ±1.5%. It operates with a low static current of 44μA and includes input interference suppression to prevent false triggering. The component provides open-drain outputs for both UV and OV events and offers a configurable reset timeout function.

Supervisors Feature Summary

• Simultaneous monitoring of two independent voltage channels
• Adjustable under-voltage and over-voltage trip thresholds
• High precision with guaranteed ±1.5% threshold accuracy
• Configurable reset timeout with shutdown capability

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Industrial control unit voltage monitoring
• Telecommunications equipment power integrity checks
• Automotive electronic control unit (ECU) protection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the DFN-8 package footprint matches the design layout. Cross-reference the exact part number with Analog Devices to avoid confusion with similar single-channel or multi-channel variants in the LTC291x family.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required within a compact form factor. The ±1.5% accuracy makes it suitable for applications demanding precise voltage tracking without external calibration. Consider the 44μA quiescent current for battery-operated designs where power efficiency is critical. Verify that the adjustable threshold range covers the specific rail voltages being monitored.

Supervisors Part Context

This part belongs to the LTC2913 series of supervisory circuits from Analog Devices. It is designed as a cost-effective solution for monitoring multiple power rails in space-constrained applications. The device integrates essential protection functions into an 8-lead DFN package, reducing board space compared to discrete solutions. It complements other PMIC offerings by providing dedicated voltage monitoring capabilities.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LTC291x family if availability is constrained. Verify that any substitute maintains the same dual-channel architecture and ±1.5% accuracy specification. Ensure the replacement supports the required operating voltage range and package type.
