LTC4413EDD Dual Low Loss PowerPath Controller

The LTC4413EDD from Linear Technology is a state-of-the-art dual PowerPath controller designed to manage power distribution between two sources in a seamless and efficient manner. This advanced component is housed in a compact DFN-10 (3mm x 3mm) package, making it an ideal choice for space-constrained applications where board real estate is at a premium.

At the heart of the LTC4413EDD lies its ability to automatically switch between two power sources, ensuring that the most suitable power supply is always in use. This is particularly useful in systems that require a backup power source or need to manage power between a battery and a wall adapter. The intelligent decision-making process of the LTC4413EDD ensures that the transition between power sources is smooth and without interruption to the load.

The controller boasts a low voltage drop due to its internal MOSFET switches, which have an on-resistance of just 140mΩ. This low loss characteristic is essential for preserving battery life and improving overall system efficiency. Additionally, the LTC4413EDD can handle up to 2.6A of continuous current, making it suitable for a wide range of applications, from portable devices to industrial systems.

One of the key features of the LTC4413EDD is its undervoltage lockout capability, which protects the system by preventing operation when the input voltage falls below a programmable threshold. This ensures that the system does not operate under conditions that could be harmful to sensitive electronic components.

The device also includes status outputs that provide real-time feedback on which power source is currently in use. These outputs can be connected to a microcontroller or other monitoring system for enhanced control and diagnostics.

Designed with practicality in mind, the LTC4413EDD requires minimal external components, simplifying design and reducing time-to-market for products that incorporate it. Overall, the LTC4413EDD is an excellent choice for designers looking for a reliable and efficient solution to manage multiple power sources in their electronic devices.
