The Texas Instruments TPS2053ADR is a state-of-the-art power distribution switch designed for applications where saving space is a critical concern. This robust component is part of the TPS205x family of power-distribution switches that are intended for USB and other hot-swap applications.

The TPS2053ADR is a single channel, current-limited, power distribution switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. With a wide input voltage range of 2.7V to 5.5V, it is suitable for a variety of other applications as well. The device ensures a seamless operation with a continuous current of 500mA across the full operating range, which makes it perfect for USB peripherals.

Key Features

• Current Limiting: Protects the host device from overcurrent conditions by limiting the output current to a safe level.
• Thermal Shutdown: Provides an additional layer of protection by shutting down the switch during over-temperature conditions.
• Under-Voltage Lockout (UVLO): Ensures that the switch remains off until the input voltage reaches a safe operating level.
• Fast Transient Response: The device reacts quickly to changes in load conditions, ensuring stable operation.
• Controlled Rise Time: Reduces inrush current, which can be beneficial in preventing nuisance trips of system protection circuits.

Applications

The TPS2053ADR is versatile and can be used in a variety of applications including:

• USB Hubs, Keyboards, and Peripherals
• Hot-Swap Power Supplies
• Portable Electronics
• Battery-Charger Circuits
