LTC4361ITS8-2

Power Management - Specialized Overview

The LTC4361ITS8-2 is an overvoltage and overcurrent protection controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5V to 80VDC and draws a supply current of 220µA. The device is housed in a TSOT-23-8 surface-mount package and functions across a temperature range of -40°C to 85°C. Designed for board-mounted surge protection, it provides precise control for disconnecting loads during fault conditions.

Power Management - Specialized Feature Summary

• Provides integrated overvoltage and overcurrent protection capabilities
• Features latch-off functionality to maintain disconnection until reset
• Designed for compact surface-mount applications

Power Management - Specialized Applications

• Handheld devices
• Mobile equipment
• Portable instrumentation

Power Management - Specialized Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status with the supplier. Check for regional sales restrictions or limited availability notices before ordering. Ensure the TSOT-23-8 footprint matches the design layout. Validate operating temperature requirements against the specified -40°C to 85°C range.

Power Management - Specialized Selection Notes

Select this component for systems requiring robust board-level surge suppression in space-constrained designs. The low supply current makes it suitable for battery-operated portable electronics. Ensure the input voltage does not exceed the 80VDC maximum rating. Consider the latch-off behavior if continuous operation during transient faults is required without manual intervention.

Power Management - Specialized Part Context

This part belongs to the LTC4361 series of overvoltage/overcurrent protection controllers from Analog Devices. It shares functional similarities with other members like the LTC4361ITS8-1 but differs in threshold settings. The series is designed to protect sensitive downstream circuitry from power supply anomalies in portable and industrial applications.
