Product Overview
The LTC4355CMS#TRPBF is a diode-OR controller from Linear Technology that offers a seamless solution for systems requiring multiple power supply paths. It's designed to replace power Schottky diodes with N-channel MOSFETs, creating an ideal diode function with significantly lower power dissipation. This component ensures continuous operation even when one source is compromised, making it invaluable in mission-critical applications where redundancy is key.
Technical Features
This device operates over a wide voltage range and provides several technical features that enhance system reliability. With its ability to control up to two N-channel MOSFETs, the LTC4355 regulates forward voltage drop across the MOSFETs to prevent reverse current and ensure smooth switchover between sources. Its 4V to 36V operating range accommodates various supply voltages, while its adjustable turn-on speed allows for customization of surge current during startup or switchover events.
Features and Applications
Ideal Diode Function: Emulates the behavior of an ideal diode using low loss N-channel MOSFETs.
Versatility: Suitable for systems such as redundant power supplies in servers and telecommunications equipment which require high reliability.
User-Friendly: Offers easy implementation into existing designs thanks to minimal external components requirement.
Safety Measures: Includes features like overcurrent protection and thermal shutdown ensuring safe operation under abnormal conditions.
The LTC4355 finds widespread use in environments where uninterrupted power supply is crucial. Examples include data centers, industrial computers, and critical communication infrastructure where dual or backup battery systems are common practice. The component's robustness also makes it well-suited for automotive applications where multiple input sources are used to guarantee consistent operation of essential electronic systems.
Models in the Same Series
The LTC4355 belongs to a family of OR controllers that share similar characteristics but may vary slightly based on specific application needs such as different voltage ratings or package types. Models within this series offer designers flexibility while maintaining consistent performance across various configurations.
Alternative Models
In cases where different specifications are needed—perhaps higher current handling capabilities or different operating temperatures—alternative models from both Linear Technology and other manufacturers can be considered. These alternatives might include variations like the LTC4357 for higher voltage applications or offerings from competitors with different feature sets that could better suit particular design requirements.
