The TPS2216DBRG4 is a sophisticated power management integrated circuit (IC) designed by Texas Instruments, specifically tailored for dual-slot PC Card applications. As a power-interface switch, it provides an efficient solution for switching and protection in systems that accommodate two PC Cards, such as PCMCIA cards, CardBus cards, or other peripherals conforming to this standard.

Key Features

• Independent Slot Control: The TPS2216DBRG4 allows for independent voltage regulation and distribution to each PC Card slot, ensuring that each device receives the correct voltage without interference from the other.
• Integrated Switches: It includes two 1-A switches for the VCC power distribution to the PC Cards, providing the necessary power for a wide range of card peripherals.
• Short-Circuit and Thermal Protection: Safety is a priority with this IC. It offers built-in short-circuit protection with automatic recovery, as well as thermal protection to prevent overheating and damage to the PC Cards and system.
• Low RDS(on): The low on-resistance of the internal switches ensures minimal voltage drop and power loss, thus improving the overall efficiency of the power distribution to the cards.

Applications

The TPS2216DBRG4 is ideal for a variety of applications that require reliable power management for dual-slot PC Card interfaces. These include:

• Notebook computers
• Portable instrumentation
• Docking stations
• File servers with PC Card expandability

Technical Specifications

The device comes in a compact 30-pin SSOP (DBR) package, making it suitable for space-constrained applications. It operates over a wide temperature range, ensuring performance in diverse operating conditions. The TPS2216DBRG4 requires minimal external components, simplifying design and reducing overall system cost.
