FAQs

What is TPS2490DGS?

The TPS2490DGS is a precision current-limiting power distribution switch designed by Texas Instruments. It is used for applications requiring precise current monitoring and protection, such as power distribution systems, hot-plug controllers, and industrial automation.

How Does TPS2490DGS Work?

The TPS2490DGS works by continuously monitoring the load current flowing through the power distribution switch. When the current exceeds a specified threshold, the TPS2490DGS limits the current to protect downstream components. It ensures reliable and safe operation of the load under varying conditions.

How Many Pins does TPS2490DGS have and What are the Functions of the Pinout Configuration?

The TPS2490DGS is housed in a 10-lead VSSOP (Very Small Outline Package) package. The pinout configuration includes:

  • IN: Current sense input for monitoring load current.
  • ILIM: Current limit setting pin for configuring the current threshold.
  • FLT: Fault indicator output pin for indicating overcurrent conditions.
  • EN: Enable pin for turning the switch on or off.
  • PGND, VOUT, GATE, VUVLO: Ground, output voltage, gate control, and undervoltage lockout pins.
  • VCC: Power supply pin.

What are the Pros and Cons of TPS2490DGS?

Pros:

  • Precision Current Limiting: Provides accurate current monitoring and limiting to protect downstream components.
  • Efficient Protection: Ensures reliable operation by limiting current during fault conditions.
  • Compact Package: The 10-lead VSSOP package is space-saving, suitable for small designs.
  • Overcurrent Indicator: Includes a fault indicator output for easy detection of overcurrent events.
  • Flexible Enable Function: Enables easy control of the power switch with the enable pin.

Cons:

  • Complex Setup: Requires proper configuration of the current limit threshold for specific applications.
  • External Components: May need additional external components for certain system requirements.
  • Operating Range: Limited to current monitoring and protection applications.

Are There Any Equivalents/Alternatives to TPS2490DGS for Recommendation?

  • The TPS2491 from Texas Instruments is a similar current-limiting power distribution switch with additional features.
  • Alternatives to the TPS2490DGS include the LTC4225 from Analog Devices and the MAX16028 from Maxim Integrated.
