```

---

| | --| EN1 OUT1 |-- --| EN2 OUT2 |-- --| GND IN1 |-- --| GND IN2 |-- |___________| ```

Pin Description: - EN1, EN2: Enable Inputs for Channel 1 and Channel 2, respectively. - OUT1, OUT2: Output Pins for Channel 1 and Channel 2, respectively. - IN1, IN2: Input Pins for Channel 1 and Channel 2, respectively. - GND: Ground Pin.

Functional Features

• Overvoltage Protection: The TPS2052BDR monitors the input voltage and disconnects the output when it exceeds a predefined threshold, protecting downstream components.
• Overcurrent Protection: This IC limits the output current to prevent damage caused by excessive load conditions.
• Fast Fault Response: The TPS2052BDR quickly detects fault conditions and disables the output within microseconds, minimizing potential damage.
• Enable Control: The enable inputs (EN1 and EN2) allow for independent control of each channel, enabling selective power distribution.

Advantages and Disadvantages

Advantages: - Wide input voltage range allows compatibility with various power sources. - Low on-resistance reduces power losses and improves efficiency. - Compact package enables use in space-constrained applications. - Adjustable overcurrent protection threshold provides flexibility.
