LTC4364HMS-1#TRPBF

Overview

The LTC4364HMS-1#TRPBF is a Surge Stopper with Ideal Diode controller manufactured by Analog Devices Inc. It operates within a voltage range of 4V to 80V and utilizes an external N-channel MOSFET for power transmission. The device features latch-off protection that disables the MOSFET upon detecting persistent faults until manually reset. It provides reverse input protection down to -40V and reverse output protection down to -20V. The component is housed in a 16-MSOP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates latch-off fault response mechanism to disable external MOSFET during persistent errors
• Includes ideal diode controller to minimize forward voltage drop and reduce power loss
• Provides bidirectional protection against reverse input voltages down to -40V
• Supports adjustable output clamp voltage via external resistor network

Applications

• Automotive load dump protection
• Avionics power system transient suppression
• Industrial equipment surge protection
• Portable instrumentation power management

Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the specific -1 variant matches the required latch-off functionality, as other variants may differ. Ensure the MSOP-16 package dimensions align with the target PCB footprint. Cross-reference the manufacturer's latest product change notifications to verify current manufacturing site and material specifications before finalizing procurement orders.

Selection Notes

Select this component when high-voltage transient immunity combined with low-loss power path control is required. The integrated ideal diode function eliminates the need for discrete Schottky diodes, improving efficiency. Choose this part for applications requiring automatic recovery from non-persistent faults while maintaining strict shutdown during critical failures. Consider the external MOSFET selection carefully to ensure compatibility with the controller's drive capabilities and thermal requirements.

Part Context

This component belongs to the LTC4364 family of Surge Stoppers designed for robust power line protection. Unlike standard suppressors, it combines surge limiting with active ideal diode control. The family includes various packages such as DFN and SOIC, but the HMS-1 variant specifically offers the MSOP-16 form factor. It addresses the limitations of passive protection by actively managing power flow and providing precise monitoring of input conditions.
