PMIC - Hot Swap Controllers

The LTC4231IUD-1#PBF is a member of the LTC4231 family of dual hot-swap controllers. It is designed to provide hot swap protection and active current limiting of dual power supplies when used as a single- or dual-supply hot-swap controller. The device has the ability to track changes in VIN and regulate the output in order to maintain a constant voltage on the load. The hot swap controller also features low on-resistance n-channel MOSFETs, current-limit protection, undervoltage protection, overvoltage protection, VIN tracking and a variety of other protections. In addition, the LTC4231IUD-1#PBF has a comprehensive compensation network that allows for precision control of the output voltage.

Application Fields

The LTC4231IUD-1#PBF is well suited for a variety of application fields, including:

• Power distribution systems
• Communication systems
• Test & measurement systems
• Portable instrumentation
• Computer & networking systems

In addition to its use in these fields, the LTC4231IUD-1#PBF is also suitable for applications requiring a general-purpose hot-swap controller with active current limiting.

Working Principle

The LTC4231IUD-1#PBF works by monitoring an input voltage (VIN) and actively controlling an output voltage (VOUT). By monitoring VIN and actively controlling VOUT, the LTC4231IUD-1#PBF can provide the necessary hot-swap protection to minimize transient faults and system stress. The device is capable of actively limiting the input current in the event of a short-circuit, allowing the device to shut down and isolate the system before any damage can occur.

The LTC4231IUD-1#PBF also features an adjustable undervoltage threshold, adjustable overvoltage threshold, inrush-limiting, and adjustable voltage-clamp to compensate for varying environmental conditions. The device is able to respond quickly to transient conditions, providing precision control of the output voltage and efficient out-of-regulation performance. The device also has built-in safeguards, such as current-limit protection, to protect itself and the system from possible damage.

The LTC4231IUD-1#PBF is a highly advanced dual hot-swap controller, providing precise control of the output voltage in a wide range of applications. The device\'s protection, current-limit and tracking capabilities make it perfect for use in power distribution, communication and test and measurement systems.
