FAQs

What is TPS26621DRCT?

The TPS26621DRCT is a hot-swap controller and power manager designed by Texas Instruments. It is ideal for applications requiring inrush current limiting, overcurrent protection, and power monitoring, such as server systems, telecom equipment, and industrial power supplies.

How Does TPS26621DRCT Work?

The TPS26621DRCT works by monitoring the input voltage and controlling the turn-on characteristics of an external MOSFET to limit inrush current during hot-plug events. It provides overcurrent protection by monitoring the voltage drop across an external current sense resistor and shutting off the MOSFET when the current exceeds a programmed threshold. The device also includes power monitoring features for real-time measurement of input and output power.

How Many Pins does TPS26621DRCT have and What are the Functions of the Pinout Configuration?

The TPS26621DRCT is housed in a 10-pin SON (Small Outline No-Lead) package. The pinout configuration includes:

IN: Power input pin.
PGOOD: Power good output pin.
FLT: Fault output pin.
EN: Enable pin.
ILIM: Current limit and set pin.
IADJ: Current adjustment pin.
VOUT: Voltage output pin.
VIN: Voltage input pin.
SENSE-: Negative current sense input pin.
SENSE+: Positive current sense input pin.

What are the Pros and Cons of TPS26621DRCT?

Pros:

Hot-Swap Capability: Enables safe insertion and removal of cards or modules in a live system without causing damage.
Inrush Current Limiting: Helps prevent large inrush currents that can stress system components and cause voltage droop.
Overcurrent Protection: Safeguards the system by monitoring current levels and reacting to faults.
Power Monitoring: Allows for real-time measurement of input and output power for system diagnostics.
Compact Package: The 10-pin SON package is space-efficient, suitable for space-constrained designs.

Cons:

Complexity: Requires careful consideration of load conditions and protection thresholds for optimal performance.
External Components: May need additional external components such as MOSFETs and current sense resistors for specific applications.
Thermal Considerations: Heat dissipation and thermal management may need to be addressed due to power handling capabilities.
