Pin Configuration

The DRV101FKTWT has the following pin configuration:

```

---

| | --| EN / IN |-- --| OUT |-- --| GND |-- --| VCC |-- |___________| ```

• EN / IN: Enable/Input pin
• OUT: Output pin
• GND: Ground pin
• VCC: Supply voltage pin

Functional Features

• Enable/Input Pin (EN / IN): This pin is used to enable or disable the power switch. When a logic high signal is applied, the switch turns on and allows current flow through the load. Conversely, when a logic low signal is applied, the switch turns off, cutting off the current flow.

• Output Pin (OUT): The output pin is connected to the load and provides the controlled current flow based on the input signal at the EN / IN pin.

• Overcurrent Protection: The DRV101FKTWT incorporates overcurrent protection, which limits the output current to a safe level in case of a fault condition. The overcurrent threshold can be adjusted according to the specific application requirements.

• Thermal Shutdown Protection: To prevent damage due to excessive heat, the DRV101FKTWT includes thermal shutdown protection. If the temperature exceeds the specified threshold, the power switch will shut down until the temperature returns to a safe operating range.

Advantages and Disadvantages

Advantages: - Wide operating voltage range allows for versatile applications. - Low quiescent current minimizes power consumption. - Overcurrent and thermal shutdown protection enhance safety and reliability. - Small package size enables use in space-constrained designs.

Disadvantages: - Limited maximum output current of 500mA may not be suitable for high-power applications. - Lack of built-in diagnostic features may require additional circuitry for fault detection.

Working Principles

The DRV101FKTWT operates as a high-side power switch by controlling the current flow between the supply voltage (VCC) and the load. When the EN / IN pin receives a logic high signal, the internal MOSFET turns on, allowing current to flow from VCC to the load through the output pin (OUT). Conversely, when a logic low signal is applied to the EN / IN pin, the MOSFET turns off, cutting off the current flow.

The overcurrent protection feature monitors the load current and limits it to a safe level by adjusting the overcurrent threshold. This protects both the power switch and the load from excessive current.

In case of excessive heat, the thermal shutdown protection activates, shutting down the power switch until the temperature returns to a safe operating range. This prevents damage to the device and ensures reliable operation.
