LTC4359IDCB#TRMPBF

OR Controllers, Ideal Diodes Overview

The LTC4359IDCB#TRMPBF is a positive high voltage ideal diode controller manufactured by Analog Devices Inc. It drives an external N-channel MOSFET to replace Schottky diodes, controlling the forward voltage drop across the MOSFET for smooth current delivery. The device operates within a supply voltage range of 4V to 80V and features a maximum supply current of 0.2mA. It supports a minimum operating temperature of -40°C and a maximum of 85°C. Packaged in a 6-pin DFN EP surface-mount format with dimensions of 2mm x 3mm and a maximum height of 0.75mm, it provides reverse input protection and low quiescent current modes.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging when sourcing. Confirm the IDCB variant corresponds to the industrial temperature grade (-40°C to +85°C) rather than the extended grade. Ensure the order matches the 6-pin DFN EP package type. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.

OR Controllers, Ideal Diodes Selection Notes

Select this component when designing high-voltage ideal diode applications requiring robust reverse input protection. It is suitable for replacing Schottky diodes in systems demanding reduced voltage drop and heat dissipation. Consider the 4V to 80V operating range and the need for an external N-channel MOSFET. Verify that the industrial temperature rating meets the environmental requirements of the target application.
