Key Featrues
Wide Operating Voltage Range (9V to 80V): The LTC4357 operates across a broad voltage range, making it versatile for various applications, including automotive systems and telecom infrastructure. This feature ensures reliable performance in environments with fluctuating power supplies, enhancing system stability and efficiency.
Fast Turn-Off Time (0.5µs): The controller's rapid turn-off time limits peak fault current during power disruptions, protecting connected components and reducing the risk of damage. This feature is crucial for high-availability systems where minimizing downtime and ensuring continuous operation are critical.
Replacement of Power Schottky Diode with N-Channel MOSFET: By driving an external N-channel MOSFET, the LTC4357 significantly reduces power dissipation and heat generation compared to traditional Schottky diodes. This leads to improved energy efficiency and reduced thermal management requirements, especially in high-current applications.
Smooth Switchover without Oscillation: The LTC4357 ensures seamless transition between power sources without oscillation, maintaining consistent voltage levels and preventing disruptions in sensitive electronic systems. This feature is particularly beneficial in redundant power supply configurations, ensuring uninterrupted operation.
No Reverse DC Current: The controller prevents reverse DC current flow, which can damage components or degrade system performance. This feature enhances the reliability and longevity of power management systems, especially in applications where power source switching is frequent or critical.
