The TPS2013D from Texas Instruments is a state-of-the-art power distribution switch designed for USB and other applications. It is a single-channel, current-limited, power distribution switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Integrated 70 mΩ N-Channel MOSFET
• Continuous load current up to 2.7A (max)
• Operating range: 2.7V to 5.5V
• Thermal and short-circuit protection with auto-retry
• Overcurrent and overtemperature protection
• 0.6ms typical rise time
• Under-voltage lockout
• Active-high enable
• Charge pump to drive N-channel MOSFET
• Soft start to limit inrush current

The TPS2013D is equipped with a 70 mΩ N-Channel MOSFET that allows for a continuous load current of up to 2.7A, making it capable of handling high-power demands. It operates over an input voltage range of 2.7V to 5.5V, which is suitable for USB-powered devices and other low-voltage applications.

One of the key safety features of the TPS2013D is its built-in thermal and short-circuit protection. The device automatically retries after a fault condition is removed, providing a robust solution for power distribution. Additionally, it includes overcurrent protection to prevent damage to the USB port by limiting the amount of current that can be drawn by the connected device.

The device also features an under-voltage lockout to ensure that the power switch remains off when the input voltage falls below a certain threshold, thus protecting downstream circuits. The active-high enable input allows for easy integration with microcontroller-based systems.

The TPS2013D is designed with a charge pump to efficiently drive the internal N-channel MOSFET and a soft-start mechanism to mitigate inrush current, which is particularly important in USB applications to avoid voltage droop on the bus.

With its comprehensive protection features and efficient power management, the TPS2013D is an ideal choice for designers looking to enhance the safety and reliability of their USB interfaces and other power-sensitive applications.
