TPS2491DGSRG4 Typical application Circuitry

TPS2491DGSRG4

The TPS2491DGSRG4 is a Hot Swap Power Manager IC designed by Texas Instruments. It's primarily used to control power delivery in systems where electronic cards are inserted and removed while the power is on. This chip helps manage the inrush current, thus protecting the system and the electronic cards.

Functionality of TPS2491DGSRG4

This IC operates as a Hot Swap controller, allowing electronic cards to be inserted or removed without shutting down the system. It controls inrush current, providing a safe power-up sequence for sensitive electronic components.

Application Scenarios

The TPS2491DGSRG4 is widely used in server farms, telecommunications equipment, and other modular systems where hot swapping of circuit boards is necessary. It's also suitable for applications like RAID (Redundant Array of Independent Disks) systems, network switches, and high-availability computing systems.

Key Parameter Features

- Controlled Inrush Current: Limits the initial surge of current during hot swapping.

- Under-Voltage Lockout (UVLO): Prevents operation at dangerously low voltages.

- Overcurrent Protection: Protects against excessive current draw.

- Adjustable Current Limiting: Customizable for different applications.

- Fault Protection: Includes features to protect against system faults.

- Power Good Indicator: Provides a status output signal.

- Wide Operating Voltage Range: Suitable for various system voltages.

- Thermal Shutdown: Protects against overheating.

Circuit Connection Example: Server Farm Hot Swap Application

To integrate the TPS2491DGSRG4 in a server farm for hot swapping, follow these detailed steps:

1. Power Input Connection

- VIN: Connect the main power supply to pin 8 (VIN), suitable for the system's operating voltage.

2. Ground Connection

- Ground: Attach pin 4 (GND) to the system ground.

3. Controlled Power Output

- VOUT: Connect pin 1 (VOUT) to the load or the hot-swappable board.

4. Current Sense and Limiting

- Sense Resistor: Connect a current sense resistor between pin 2 (SENSE) and pin 3 (VOUT).

- Adjust Current Limit: Use external components on pin 7 (ILIM) to set the desired current limit.

5. Under-Voltage Lockout Setup

- UVLO Configuration: Utilize pin 6 (UVLO) with external resistors to set the under-voltage lockout threshold.

6. Power Good Indicator

- Status Output: Connect pin 5 (PGOOD) to an LED or to a control system for power good indication.

7. Decoupling Capacitors

- Stabilization: Place decoupling capacitors close to the VIN and VOUT pins to stabilize the power supply and minimize noise.

8. Thermal Management

- Heat Dissipation: Ensure adequate heat sinking for the IC, especially in high-power applications.

Design Considerations

When designing with the TPS2491DGSRG4, focus on the power supply rating, current sensing and limiting, UVLO settings, fault protection features, power good indication, thermal management, and overall PCB layout for optimal performance.

In summary, the TPS2491DGSRG4 is a Hot Swap Power Manager IC, ideal for server farms and other modular systems requiring hot swapping capabilities. Its features for controlling inrush current, UVLO, overcurrent protection, and fault indication make it effective in managing the power requirements of hot-swappable systems. Proper attention to current limiting, UVLO configuration, and thermal considerations is key for successful integration into electronic systems.
