The TPS2350PWG4 is a robust, feature-rich Hot Swap Power Manager designed by Texas Instruments to facilitate the safe insertion and removal of circuit boards from live backplanes or bus systems. This power management integrated circuit (PMIC) is particularly well-suited for applications in servers, telecom, and networking equipment, where system uptime and reliability are of paramount importance.

Key Features

• Integrated Power MOSFET: The TPS2350PWG4 comes with an integrated N-channel power MOSFET that provides efficient power control and distribution, enabling the device to handle substantial current levels with minimal power dissipation.
• Adjustable Current Limit: Users can set the current limit threshold via an external resistor, allowing for precise control over the maximum current provided to the load, thereby protecting both the power source and the load from overcurrent conditions.
• Programmable Circuit Breaker: This feature enables the device to disconnect the load in the event of an overcurrent, protecting the system from damage.
• Under-Voltage Lockout (UVLO): The TPS2350PWG4 ensures that the system operates within safe voltage levels by monitoring the input voltage and turning off the power path when it falls below a preset threshold.
• Overvoltage Protection: To safeguard the downstream circuitry, the device includes overvoltage protection that triggers if the input voltage exceeds a certain limit.
• Power Good Output: This output signal can be used to indicate that the output voltage is within an acceptable range, allowing for downstream systems to activate only when stable power is guaranteed.
• Thermal Shutdown: The TPS2350PWG4 is equipped with a thermal shutdown feature that turns off the power path if the device temperature exceeds safe operating limits, thus preventing thermal damage.

Applications

The TPS2350PWG4 is ideal for use in a wide range of applications where power management and protection are critical. It is commonly used in:

• Network Routers and Switches
• Server and Storage Systems
• Base Stations
• Industrial Control Systems

With its comprehensive suite of protection features and the reliability of Texas Instruments, the TPS2350PWG4 is an excellent choice for managing hot-swap events and ensuring the continuous operation of critical electronic systems.
