Overview of TPS2216DBR from Texas Instruments

The TPS2216DBR is a versatile and efficient power distribution switch designed by Texas Instruments, tailored for managing power requirements in a variety of electronic applications. This integrated circuit (IC) is part of the TPS221x family and is particularly suitable for USB and other applications where heavy capacitive loads and short-circuits are likely to be encountered.

Key Features

• Dual-Slot Power Distribution: The TPS2216DBR is capable of handling two independent power distribution paths, making it ideal for systems that require multiple power channels.
• Programmable Current Limiting: The IC allows for precise control over the current supplied to each load, which can be programmed via an external resistor. This feature helps to protect both the power source and the load from overcurrent conditions.
• Fast Overcurrent Response: With a quick response time to overcurrent conditions, the TPS2216DBR can effectively prevent damage to the system by rapidly turning off the output.
• Thermal Shutdown: In-built thermal shutdown functionality further enhances the safety of the system by turning off the output if the junction temperature exceeds a safe threshold.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off when the input voltage is below a certain threshold, thus protecting the device and the load.

Applications

The TPS2216DBR is particularly well-suited for USB power distribution and hot-plug power control. Its robust design also makes it a good choice for applications such as:

• Notebook computers
• Desktop computers
• Peripheral devices
• Docking stations
• Monitors and displays

Package and Availability

The TPS2216DBR comes in a compact SSOP (Shrink Small Outline Package) with 16 pins, offering a space-saving solution for PCB designs. It is widely available through Texas Instruments' distribution network, ensuring easy access for designers and manufacturers alike.

With its combination of protective features, programmable current limiting, and dual-channel operation, the TPS2216DBR stands out as a reliable and flexible solution for power distribution in complex electronic systems.
