LTC4361ITS8-1

Power Management - Specialized Overview

The LTC4361ITS8-1 is an overvoltage and overcurrent protection controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 80 V DC and draws a maximum supply current of 400 µA. The device is housed in a TSOT-23-8 surface-mount package with dimensions of 2.9 mm x 1.75 mm x 0.9 mm. It functions as a board mount surge protector, providing precise control for system protection against electrical faults.

Power Management - Specialized Feature Summary

• Provides integrated overvoltage and overcurrent protection capabilities
• Features latch-off functionality for robust fault handling
• Designed for low static current operation to conserve power

Power Management - Specialized Applications

• USB port protection circuits
• Handheld computer power management
• Mobile device input protection

Power Management - Specialized Procurement Notes

Verify component status carefully as the LTC4361ITS8-1#PBF variant is listed as discontinued or end-of-life by major distributors. Confirm availability of the tape-and-reel version (LTC4361ITS8-1#TRMPBF) if production continuity is required. Ensure the specific suffix matches the required packaging format for your assembly line.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring compact overvoltage and overcurrent protection for inputs up to 80 V. The TSOT-23-8 package suits space-constrained portable applications. Verify that the latch-off behavior aligns with the system's reset strategy, as manual intervention may be necessary after a fault event compared to auto-retry variants.

Power Management - Specialized Part Context

This part belongs to the LTC4361 series of overvoltage/overcurrent protection controllers from Analog Devices. The series includes variants like the LTC4361-2 which may offer different pin configurations or functional options. These devices are categorized under PMIC and surge suppressors, targeting high-reliability protection for sensitive electronics in mobile and industrial environments.

Power Management - Specialized Replacement Considerations

Public confirmed substitute part numbers include LTC4361ITS8-2#TRMPBF and LTC4361CTS8-1#TRMPBF. Verify pin compatibility and specific feature differences between the -1 and -2 suffixes before substitution.
