Pin Configuration

The TPS2552DRVR has the following pin configuration:

```

---

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

• EN: Enable pin for controlling the load switch.
• OUT: Output pin connected to the load.
• GND: Ground reference pin.
• IN+: Positive input voltage pin.
• IN-: Negative input voltage pin.
• ILIM: Current limit adjustment pin.

Functional Features

1. Overcurrent Protection: The TPS2552DRVR monitors the load current and automatically shuts off the output when it exceeds the set current limit.
2. Load Switching: It allows for controlled switching of the load, providing a convenient way to turn on/off power to connected devices.
3. Adjustable Current Limit: The current limit can be adjusted according to the specific requirements of the application.
4. Undervoltage Lockout: The device ensures that the output voltage remains within a safe range by disabling the load switch when the input voltage drops below a certain threshold.
5. Low-Power Shutdown Mode: In this mode, the TPS2552DRVR consumes minimal power, making it suitable for battery-powered applications.
6. Thermal Shutdown Protection: It incorporates thermal protection to prevent overheating and potential damage to the device.

Advantages and Disadvantages

Advantages

• Efficient power distribution and protection.
• Wide input voltage range.
• Adjustable current limit for flexibility.
• Compact package size.
• Thermal shutdown protection enhances reliability.

Disadvantages

• Limited maximum current handling capability (up to 1.5A).
• Requires external components for complete functionality.

Working Principles

The TPS2552DRVR operates by monitoring the load current through the ILIM pin. When the load current exceeds the set current limit, the device quickly shuts off the load switch to protect the connected circuitry. It also incorporates undervoltage lockout to prevent operation at unsafe input voltage levels. The adjustable current limit feature allows customization based on the specific requirements of the application.
