LTC4364HDE-1#TRPBF

Overview

The LTC4364HDE-1#TRPBF is a board mount surge stopper with an integrated ideal diode controller, manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 80V and withstands high-voltage transients up to 250V. The device features a -40°C to +125°C operating temperature range and utilizes a 14-pin DFN package. In the event of a fault, the component enters a latched-off state, requiring manual intervention to reset. It provides comprehensive protection against overvoltage, reverse polarity, and short circuits for sensitive loads.

Feature Summary

• Active clamping and limiting of high-voltage transients to protect downstream circuitry
• Integrated ideal diode controller replaces external Schottky diodes to minimize forward voltage drop
• Latched-off fault response mode ensures system safety until manual reset occurs
• Bidirectional protection capabilities including reverse input and output isolation

Applications

• Protection of sensitive loads in industrial automation systems
• Surge suppression for automotive electronic control units
• Power input protection for robotics and motor drive applications
• High-voltage transient mitigation in remote monitoring equipment

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the HDE designation corresponds to the extended industrial temperature range requirements of your application. Ensure compatibility with the 14-pin DFN footprint during PCB layout finalization. Cross-reference the datasheet for exact pinout configurations to prevent installation errors.

Selection Notes

Select this model specifically for applications requiring a latched-off response to faults rather than automatic retry. The HDE variant is necessary for environments exceeding commercial temperature limits. Consider the LTC4364HDE-2 if automatic recovery after a cooldown period is preferred. Evaluate external MOSFET selection to ensure current handling matches the surge stopper's capabilities.

Part Context

This component belongs to the LTC4364 series of surge stoppers designed for robust power input protection. The series includes variants with different fault responses and temperature ratings. The HDE suffix denotes industrial grade performance, while the -1 suffix specifies the latched-off behavior. This family addresses the need for reliable protection against severe electrical disturbances in harsh operating conditions.

Replacement Considerations

The LTC4364HDE-2 serves as a functional alternative if automatic retry behavior is acceptable instead of latching off. Other series members like LTC4364CDE-1 offer similar functionality but are limited to commercial temperature ranges.
