LT4351IMS#PBF

Power Management Integrated Circuits (PMICs) are a form of Integrated Circuit (IC) used to manage and regulate a system\'s power. They are generally divided into two categories; OR controllers, and ideal diodes. The LT4351IMS#PBF is an example of a OR controller, an integral component for achieving power distribution in numerous systems.An OR controller allows for the combination of two independent power supplies, both of which are capable of supplying the full load current, into a single output system. An OR controller provides an integrated approach to achieve a stable interconnect between both power sources, without disruption from either one. The LT4351IMS#PBF acts as an OR controller, utilising a single pin selector with a voltage-controlled switch to determine which power source to draw power from at any given moment.In most applications, there are two primary sources of power: a backup power source and a main power source. The main power source supplies the vast majority of the power needs, while remaining operational at all times. The backup power source is used when the primary source fails, either to provide an uninterrupted power supply, or to prevent loose connections in the system. The LT4351IMS#PBF is designed to provide an integrated OR controller solution, allowing both sources of power to be used in tandem.The LT4351IMS#PBF is configured with a single pin selector at its input. This selector determines which power source is actively supplying the system, either the main power source, or the backup power source. Once the selector determines the active source, the LT4351IMS#PBF then regulates the load current from the primary source to the active source.The LT4351IMS#PBF is capable of managing a voltage input from either the main power source or the backup power source, and can provide up to 1.5 A of current. It has a wide range of features, including four distinct operating and fault conditions. It is designed to be extremely efficient, with a low power dissipation of less than 1.5 W.A key benefit of the LT4351IMS#PBF is its ability to provide a constant, uninterrupted power supply for critical applications. By using an OR controller, the system is capable of automatically switching from the primary power source to the backup power source when the primary source is depleted, without disruption to the system. This helps to ensure reliable power supply to systems that are sensitive to power fluctuations.In summary, the LT4351IMS#PBF provides an ideal OR controller solution for achieving power distribution in numerous systems. It utilizes a single pin selector to determine which power source is actively supplying the system, and is capable of handling up to 1.5 A of current. Additionally, it helps to ensure a constant power supply for critical applications.
