TPS2491DGSR Typical application Circuitry

TPS2491DGSR

The TPS2491DGSR is an integrated circuit designed as a hot-swap controller and power manager. This chip is typically used in systems where it's necessary to insert or remove boards without turning off the system power, such as in server farms, telecommunications, and network routers.

1. Primary Functionality: The TPS2491DGSR acts as a hot-swap controller, allowing electronic boards to be safely inserted and removed from a live backplane. It manages power distribution and limits inrush current to protect the system and the board being hot-swapped.

2. Application Scenarios: Commonly used in data centers, telecommunications equipment, and network systems where continuous operation is critical and downtime for maintenance or upgrade is not desirable.

3. Key Features: The TPS2491DGSR includes features like programmable current limit, overvoltage and undervoltage lockout, fast short-circuit response, and a charge pump for controlling external N-channel MOSFETs.

4. Circuit Integration in a Server System:

- VIN (Pin 1): Connect to the system's power supply (12V-48V typically in server applications).

- VOUT (Pin 2): Connect to the load or the board being inserted into the system.

- SENSE (Pin 3): Attach a sense resistor between this pin and VOUT for current sensing.

- GATE (Pin 4): Connect to the gate of an N-channel MOSFET used for controlling power flow.

- ON/OFF (Pin 5): Link to a control signal or switch for enabling or disabling the hot-swap function.

- UVLO, OVLO (Pins 6, 7): Set under-voltage and over-voltage lockout levels using resistive dividers from the power supply.

- GND (Pin 8): Connect to the system ground.

5. Design Considerations:

- Power Supply Stability: Ensure the input power supply is stable and within the operating range of the TPS2491DGSR.

- Proper Heat Dissipation: As hot-swap controllers can handle high current, ensure adequate heat sinking for the MOSFET and the controller itself.

- Correct MOSFET Selection: Choose an N-channel MOSFET compatible with the current and voltage requirements of the application.

- Accurate Sensing: Implement precise current sensing for effective current limit control.

In conclusion, the TPS2491DGSR is a highly efficient hot-swap controller and power manager, crucial in applications where boards need to be inserted or removed from live systems without causing interruptions or damage. Its implementation in server systems exemplifies its ability to manage power safely and effectively. When designing circuits with the TPS2491DGSR, considerations such as power supply stability, heat dissipation, MOSFET selection, and accurate sensing are paramount. This chip, with its advanced features, ensures the reliability and continuity of operations in critical electronic systems.
