TPS2350DR

TPS2350DR Description

The TPS2350DR is a high-performance hot swap controller designed to manage the insertion and removal of circuit boards in live systems, ensuring reliable and safe operation. Manufactured by Texas Instruments, this device is a key component in power management solutions, particularly in systems requiring robust protection against voltage transients current and surges.

The TPS2350DR features a surface mount package, making it suitable for high-density printed circuit board (PCB) designs. It is available in a 14SOIC package, which is both compact and durable. The device is designed to operate with a -48V supply, making it ideal for telecommunications and networking applications where such voltage levels are common.

This hot swap controller is equipped with three channels, providing flexibility in managing multiple power inputs or outputs. It does not include internal switches, allowing for external MOSFETs to be used, which can be optimized for specific system requirements. The TPS2350DR also supports programmable features such as current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO), offering a high degree of customization and control.

TPS2350DR Features

The TPS2350DR offers several unique features that set it apart from similar models in the market:

• Auto Retry Functionality: This feature allows the device to automatically attempt to re-establish a connection after a fault has been cleared, reducing downtime and improving system reliability.
• Programmable Features: The ability to program current limit, fault timeout, OVP, slew rate, and UVLO provides system designers with the flexibility to tailor the device to their specific application needs.
• Surface Mount Technology (SMT): The surface mount package type ensures ease of integration into modern PCB designs, facilitating automated assembly processes and reducing overall footprint.
• Compliance and Standards: The TPS2350DR is REACH unaffected and RoHS3 compliant, ensuring it meets environmental and safety standards for electronics manufacturing. It also carries the ECCN classification of EAR99, indicating its compliance with export regulations.
• Moisture Sensitivity Level (MSL): With an MSL of 1 (Unlimited), the TPS2350DR is suitable for storage and handling in a wide range of environmental conditions without the need for special precautions.
