LTC4364HMS-2#PBF

Overview

The LTC4364HMS-2#PBF is a board mount surge protector and ideal diode controller manufactured by Analog Devices Inc. It operates within a voltage range of 4 VDC to 80 VDC with a supply current of 750 uA. The device is housed in an MSOP-16 package, measuring 4 mm in length, 3 mm in width, and 0.86 mm in height. It supports surface mount technology and functions across a temperature range from -40°C to +125°C.

Feature Summary

• Integrates surge stopper functionality with ideal diode control for comprehensive power path protection
• Features latch-off fault response mechanism that locks out the external MOSFET during persistent faults until manually reset
• Provides bidirectional reverse input protection down to -40V and reverse output protection down to -20V

Applications

• Automotive systems requiring robust load dump protection
• Avionics power distribution networks
• Industrial equipment needing high-voltage transient suppression

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details via official documentation. Check for recent Product Change Notifications regarding manufacturing site or material updates. Ensure storage conditions meet moisture sensitivity requirements prior to assembly.

Selection Notes

Select this variant for applications requiring extended industrial temperature ranges up to 125°C. The MSOP-16 package offers a compact footprint suitable for dense PCB layouts. Consider the latch-off feature if system safety requires definitive fault isolation rather than automatic recovery. Validate external MOSFET selection against the controller's drive capabilities.

Part Context

This component belongs to the LTC4364 series of Surge Stopper devices. It combines overvoltage protection with ideal diode rectification in a single integrated circuit. The series is designed to protect sensitive loads from input transients while minimizing power loss in the main power path compared to traditional diode solutions.

Replacement Considerations

LTC4364IMS-2#PBF serves as a commercial grade alternative with a lower maximum operating temperature of 85°C. Verify thermal requirements before substitution. Other variants like LTC4364HDE-2 offer different packaging options such as DFN.
