LTC2966HUD#PBF

Supervisors Overview

The LTC2966HUD#PBF is a low current, high voltage dual channel voltage monitor manufactured by Analog Devices. It features internal high-value resistors to sense input monitor pins, providing a compact solution for supervising multiple voltage rails. The device operates with a supply voltage range of 2.5V to 100V and includes an open-drain or open-collector output. It is housed in a 16-lead QFN package (3x3mm) suitable for surface mount applications.

Supervisors Feature Summary

• Dual channel voltage monitoring capability with integrated high-value sensing resistors
• High voltage operation supporting inputs up to 100V
• Low quiescent current consumption for power-sensitive designs
• Configurable open-drain or open-collector fault output

Supervisors Applications

• Industrial control systems requiring multi-rail supervision
• Automotive electronics monitoring high-voltage bus lines
• Telecommunications infrastructure power management
• Server and storage system voltage oversight

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the HUD variant meets industrial temperature specifications. Ensure the 16-QFN package dimensions align with PCB footprint requirements. Check for any recent lifecycle status changes or obsolescence notices from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual-channel supervision is required within a single package to save board space. The internal resistors eliminate external components, simplifying design. Consider the 100V input range if monitoring higher voltage rails directly. Evaluate the low current draw against system power budgets. Compare against single-channel monitors if only one rail requires supervision.

Supervisors Part Context

The LTC2966 belongs to Analog Devices' line of voltage supervisors designed for high-voltage applications. It complements other PMIC devices by offering precise monitoring without complex external circuitry. The QFN package allows for dense layout configurations in modern electronic equipment where space efficiency is critical.

Supervisors Replacement Considerations

Direct substitutes may include other dual-channel high-voltage monitors from Analog Devices such as the LTC2965 or LTC2967 series, depending on channel count and voltage requirements. Verify pin compatibility and electrical specifications before substitution.
