Detailed Pin Configuration

The TPS2068DG4 has eight pins arranged as follows:

```

---

| | --| VCC | --| GND | --| EN | --| FAULT | --| OUT1 | --| OUT2 | |___________| ```

• VCC: Power supply input
• GND: Ground reference
• EN: Enable pin to control the IC's operation
• FAULT: Output pin indicating fault conditions
• OUT1, OUT2: Power output pins

Functional Features

• Overcurrent Protection: The TPS2068DG4 monitors the current flowing through each channel and shuts down the corresponding output if it exceeds a predefined threshold.
• Undervoltage Lockout: This feature ensures that the output voltage remains within acceptable limits by disabling the outputs when the input voltage falls below a specified level.
• Thermal Shutdown: In case of excessive temperature, the IC automatically disables the outputs to prevent damage.

Advantages and Disadvantages

Advantages

• Efficient power distribution and protection for electronic systems
• Wide input voltage range allows for versatile applications
• Compact package size for space-constrained designs
• Multiple channels enable simultaneous control and protection of different power lines

Disadvantages

• Limited maximum continuous current per channel (1.5A)
• Relatively high quiescent current compared to some alternative models

Working Principles

The TPS2068DG4 operates by continuously monitoring the input voltage and current on each channel. It compares these values against predefined thresholds to detect fault conditions such as overcurrent or undervoltage. When a fault is detected, the IC takes appropriate action, such as disabling the affected output or shutting down the entire system in case of thermal overload.
