Product Overview: TPS2391DGKR by Texas Instruments

The TPS2391DGKR from Texas Instruments is a high-performance, positive high-voltage hot swap controller designed to enable the safe insertion and removal of circuit boards from live backplanes. The device is housed in an 8-pin MSOP (DGK) package and is part of Texas Instruments' extensive power management integrated circuits portfolio.

Key Features

• Integrated Charge Pump: The TPS2391DGKR features an on-chip charge pump that provides the gate drive for an external N-channel MOSFET, enabling efficient control of the power to the load without the need for additional external components.
• Adjustable Current Limit: Users can set the current limit threshold through an external resistor, providing flexibility to accommodate various applications and protection levels.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates only when the supply voltage is within a specified range, preventing damage from undervoltage conditions.
• Fast Overcurrent Response: The TPS2391DGKR is designed to respond quickly to overcurrent conditions, helping to protect both the backplane and the card being inserted or removed.
• Power Good Output: This feature provides a signal indicating when the output voltage is within a specified range, which is useful for downstream load management and sequencing.

Applications

The TPS2391DGKR is suitable for a wide range of applications where hot swap capability is required, including:

• Telecommunications Equipment
• Network Servers and Routers
• Data Storage Systems
• Industrial Systems
