LTC4361HDC-1#TRMPBF

Power Management - Specialized Overview

The LTC4361HDC-1#TRMPBF is an overvoltage and overcurrent protection controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5V to 80V and draws a typical supply current of 220µA. The device is housed in an 8-WFDFN (2x2) package with exposed pad, suitable for surface mount installation. It functions as a board-mount surge protector designed to safeguard downstream circuitry from power line anomalies.

Power Management - Specialized Feature Summary

• Provides integrated control for external N-channel MOSFETs to isolate loads during fault conditions
• Features adjustable thresholds for both overvoltage and overcurrent protection events
• Includes internal delay timers to prevent nuisance tripping from transient spikes

Power Management - Specialized Applications

• Handheld computers
• Mobile devices
• Portable electronics

Power Management - Specialized Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's latest datasheet before ordering. Confirm that the 8-DFN footprint matches your PCB layout constraints. Ensure compatibility with your system's voltage levels and current requirements. Check for any recent design changes or obsolescence notices from Analog Devices.

Power Management - Specialized Selection Notes

Select this component when high input voltage tolerance up to 80V is required in a compact form factor. Consider the low quiescent current for battery-powered applications. Evaluate the need for external MOSFET selection based on load current and RDS(on) requirements. Compare pinout and thermal performance against alternative DFN packages if space is constrained.

Power Management - Specialized Part Context

This part belongs to the LTC4361 series of hot-swap and protection controllers. It complements other variants like the ITS8 and CTS8 packages within the same functional family. The HDC-1 designation indicates the specific 8-DFN package configuration optimized for dense PCB layouts.

Power Management - Specialized Replacement Considerations

Direct substitutes include other LTC4361 variants such as LTC4361ITS8-1#PBF or LTC4361CTS8-1#TRMPBF, provided the package difference is accommodated in the design. Verify pin-to-pin compatibility and electrical specifications before swapping.
