```

---

| | --| EN OUT |-- --| GND IN- |-- --| IN+ FLT |-- |___________| ```

1. EN: Enable pin for controlling the power distribution.
2. OUT: Output pin for connecting to the load.
3. GND: Ground reference pin.
4. IN-: Negative input pin for the power supply.
5. IN+: Positive input pin for the power supply.
6. FLT: Fault flag output pin indicating overcurrent conditions.

Functional Features

• Overcurrent Protection: The TPS2561DRCR monitors the current flowing through the load and shuts down the power distribution if it exceeds a predefined threshold.
• Hot-Plug Support: This PMIC allows devices to be inserted or removed while the power is still applied, without causing any disruption or damage.
• Low Voltage Drop: The TPS2561DRCR minimizes voltage drop across the power distribution path, ensuring efficient power delivery to the load.

Advantages and Disadvantages

Advantages

• Efficient power distribution with low voltage drop.
• Overcurrent protection safeguards connected devices.
• Hot-plug support enables seamless device insertion and removal.
• Wide input voltage range accommodates various power supply configurations.
