LTC4365HDDB#TRPBF

Power Management - Specialized Overview

The LTC4365HDDB#TRPBF is a board mount surge protector and overvoltage/undervoltage/reverse supply protection controller manufactured by Analog Devices Inc. It operates within a voltage range of 2.5 V to 34 V and features a low supply current of 125 µA. The device is housed in an 8-WFDFN package with dimensions of 3 mm x 2 mm x 0.75 mm, utilizing SMD/SMT termination. It supports operation across a temperature range of -40°C to +125°C.

Power Management - Specialized Feature Summary

• Provides comprehensive protection against overvoltage, undervoltage, and reverse polarity events for sensitive loads.
• Controls external N-channel MOSFETs to manage power path integrity during fault conditions.
• Features low quiescent current consumption suitable for battery-powered applications.

Power Management - Specialized Applications

• Portable instrumentation
• Industrial automation systems

Power Management - Specialized Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the HDDB variant corresponds to the correct DFN-8 footprint requirements for your PCB layout. Ensure compatibility with the intended operating voltage range before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component for applications requiring robust input protection without internal switching capabilities. Consider the external MOSFET requirement for current handling. Evaluate the 125 µA supply current against system power budgets. Verify thermal performance within the specified -40°C to +125°C operational window.

Power Management - Specialized Part Context

This part belongs to the LTC4365 series of protection controllers from Analog Devices. It is designed specifically for safeguarding downstream circuitry from input power anomalies. The device functions as a controller rather than a standalone switch, necessitating external pass elements for high-current paths.

Power Management - Specialized Replacement Considerations

LTC4365HDDB#TRMPBF is a confirmed substitute offering identical electrical specifications but in tube packaging instead of tape and reel.
