LTC4380CMS-1#PBF - Surge Stopper from Linear Technology

The LTC4380CMS-1#PBF is a state-of-the-art surge stopper designed by Linear Technology to provide reliable protection for low power systems against high voltage surges and overcurrent conditions. This component is an essential safeguard for sensitive electronics, ensuring operational stability and extending the lifespan of the end product.

At the heart of the LTC4380CMS-1#PBF lies its ability to control an external N-channel MOSFET to act as a variable resistor, dynamically adjusting to varying input voltages and currents. This innovative feature allows the device to clamp the output voltage during an overvoltage event, such as a load dump in automotive applications or power surges in industrial systems, thereby protecting downstream components from damage.

The LTC4380CMS-1#PBF operates over a wide input voltage range of 4V to 72V, making it versatile for a variety of applications. It is capable of withstanding transient overvoltages up to 80V, ensuring robust performance even in the most demanding environments. The device also integrates a low quiescent current, typically 7µA in shutdown and 50µA in operation, which is particularly beneficial for battery-powered applications where power efficiency is crucial.

Fault protection is further enhanced by the inclusion of overcurrent protection, featuring a fast response to prevent potential damage from short-circuit events or excessive load currents. An adjustable undervoltage lockout (UVLO) is also provided, preventing the system from operating at dangerously low voltages that could compromise performance or stability.

The LTC4380CMS-1#PBF comes in a compact 10-lead MSOP package, offering a space-saving solution without compromising on functionality. Its operating temperature range of -40°C to 125°C assures reliable operation across a broad spectrum of temperature conditions.

Whether you're designing automotive electronics, industrial control systems, or portable devices, the LTC4380CMS-1#PBF surge stopper from Linear Technology is an excellent choice for protecting your sensitive circuits against voltage and current transients, ensuring your products operate safely and reliably.
