LTC2965HDD#PBF

Supervisors Overview

The LTC2965HDD#PBF is a high-precision, dual-channel digital power monitor from Analog Devices. It features integrated current sense amplifiers and voltage references to measure supply voltages and currents with high accuracy. The device communicates via an I2C-compatible interface, allowing for real-time monitoring of power rails in complex systems. It includes programmable thresholds for over-voltage and under-voltage protection, as well as over-current detection capabilities.

Supervisors Feature Summary

• Dual-channel measurement capability for simultaneous monitoring of two independent power supplies
• Integrated high-side current sensing with low offset voltage for accurate load current measurement
• Programmable fault response options including latching or auto-retry modes for system protection
• I2C digital interface for easy integration with microcontrollers and data acquisition systems

Supervisors Applications

• Server and storage system power rail monitoring
• Telecommunications infrastructure equipment
• Industrial control systems requiring precise power management
• Networking switches and routers

Supervisors Procurement Notes

Verify the specific suffix (PBF) indicates lead-free compliance and RoHS adherence when ordering. Confirm the package type (DD) matches your PCB footprint requirements. Ensure the operating temperature range meets your application's environmental conditions. Check for any specific revision differences that might affect pin compatibility or register maps.

Supervisors Selection Notes

Select this component when dual-channel monitoring is required within a single IC. Consider the accuracy specifications relative to your system's tolerance needs. Evaluate the I2C address configuration options to avoid bus conflicts. Assess the need for integrated fault handling versus external logic implementation.

Supervisors Part Context

This part belongs to the LTC296x family of digital power monitors. It offers a compact solution compared to discrete designs using separate amplifiers and ADCs. The family provides various channel counts and interface options to suit different complexity levels in power management architectures.

Supervisors Replacement Considerations

Direct replacements may include other LTC296x variants with different channel counts or interfaces. Verify pin-to-pin compatibility if substituting with similar parts from Analog Devices or competitors. Ensure functional equivalence in terms of accuracy, speed, and fault handling mechanisms.
