Introducing the TPS2090D Power Distribution Switch from Texas Instruments

The TPS2090D, crafted by the renowned semiconductor company Texas Instruments, is a versatile and reliable power distribution switch designed for applications that require multiple power switches in a single package. This advanced component is a part of TI's extensive portfolio of power management solutions, engineered to enhance system reliability and extend battery life in portable and distributed power systems.

Key Features and Benefits

• Dual-Channel Configuration: The TPS2090D features two independent 0.7A current-limited power switches, offering designers the flexibility to control two separate loads with a single device.
• Built-in Overcurrent Protection: Each channel is equipped with current-limiting and thermal shutdown features to protect against excessive current draw and overheating, safeguarding both the switch and the downstream circuitry.
• Fast Transient Response: The device provides a quick response to overcurrent events, minimizing the risk of system damage.
• Low On-Resistance: With a low on-resistance of typically 70mΩ per channel, the TPS2090D ensures minimal voltage drop and power loss, thereby improving overall system efficiency.
• Undervoltage Lockout (UVLO): The UVLO feature prevents the switch from turning on when the input voltage is below a certain threshold, ensuring stable operation under varying supply conditions.
• Controlled Rise Time: The device offers a controlled output rise time, which reduces inrush current and mitigates potential voltage spikes during power-up.
• Logic-Level Enable Inputs: Each channel can be independently controlled via TTL-compatible enable inputs, providing precise control over power sequencing.

Applications

The TPS2090D is ideal for a broad range of applications, including:

• USB hubs and peripherals
• Hot-swap supplies
• Notebook computers
• Portable electronics

With its dual-channel design, comprehensive protection features, and efficient performance, the TPS2090D from Texas Instruments is a top choice for designers looking to enhance power distribution in their next project. Its compact SOIC-8 package makes it a space-saving addition to any PCB layout.
