LTC2913HDD-2#PBF

Supervisors Overview

The LTC2913HDD-2#PBF is a dual input voltage monitor from Analog Devices, designed for supervising multiple power rails in complex systems. It operates within a supply voltage range of 1.02V to 5.5V and features two independent monitoring channels with factory-set thresholds. The device utilizes a DFN-10 package for compact integration. Key electrical characteristics include a low quiescent current of 40µA and a reset timeout delay of 140ms. It supports active-low or active-high reset outputs and includes an open-drain manual reset input for system control.

Supervisors Feature Summary

• Dual-channel supervision for independent voltage monitoring
• Factory-set threshold voltages eliminate external resistor networks
• Manual reset input allows software-controlled assertion
• Compact DFN-10 package suitable for space-constrained designs

Supervisors Applications

• Multi-rail power supply monitoring in industrial equipment
• Voltage supervision in embedded computing systems
• Power management in telecommunications infrastructure

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance and tube packaging. Confirm the -HDD package variant matches your PCB footprint requirements. Ensure the -2 suffix corresponds to the correct factory-set threshold configuration for your application voltages. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required without external precision resistors. The fixed thresholds simplify design but limit flexibility compared to adjustable supervisors. Consider the 40µA quiescent current for battery-sensitive applications. Verify that the 140ms timeout meets the system's recovery timing requirements. The DFN-10 package offers thermal performance benefits over larger packages.

Supervisors Part Context

Part of the LTC2912/2913 family of supervisory circuits. Shares functional similarities with LTC2912 but adds a second monitoring channel. Complements other PMIC components like the LTC2914 for comprehensive power management. Designed for reliability in harsh environments with wide operating temperature ranges.

Supervisors Replacement Considerations

LTC2913IDD-1#TRPBF offers similar functionality with different threshold settings and tape-and-reel packaging. LTC2913HDD-2#TRPBF provides identical electrical specifications but in reel format instead of tube. Verify pinout compatibility before substitution to ensure seamless integration into existing designs.
