LTC4364IMS-2#TRPBF

Overview

The LTC4364IMS-2#TRPBF is a board mount surge stopper manufactured by Analog Devices Inc., designed to protect sensitive loads from high voltage transients. It operates within a voltage range of 4 VDC to 80 VDC and features an MSOP-16 surface-mount package with SMD/SMT termination. The device supports an operating temperature range from -40°C to +85°C and draws a quiescent current of 750 uA. This component integrates ideal diode functionality and controls external N-channel MOSFETs to limit and clamp output voltages during overvoltage events, such as automotive load dumps.

Feature Summary

• Integrates ideal diode controller to replace traditional Schottky diodes, reducing forward voltage drop and power loss.
• Controls external N-channel MOSFETs to actively limit and clamp output voltage during overvoltage transients.
• Provides bidirectional protection against reverse input and reverse output conditions.
• Features automatic retry mode (0.1% duty cycle) following fault detection for unattended system operation.

Applications

• Automotive systems requiring protection against load dump events
• Avionics power distribution networks
• Industrial equipment power inputs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IMS variant corresponds to the MSOP-16 package type required for the target PCB layout. Ensure the -2 suffix aligns with the desired automatic retry fault response behavior rather than latched-off operation. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm RoHS compliance and current availability status.

Selection Notes

Select this component when designing circuits requiring protection between 4V and 80V with integrated ideal diode functionality. The -2 suffix is appropriate for applications needing automatic recovery after faults. Consider the MSOP-16 package dimensions and thermal characteristics for board space constraints. Verify that the external MOSFET selection matches the controller's drive capabilities and current ratings.

Part Context

This part belongs to the LTC4364 series of Surge Stoppers with Ideal Diode controllers. The series includes variants with different temperature ranges and fault response modes, such as the LTC4364CDE and LTC4364HDE families. The IMS-2 designation specifically denotes the commercial/industrial temperature grade with automatic retry functionality in a 16-lead MSOP package.
