TPS2041BDBVR/TPS2041BDBVT - Texas Instruments

The TPS2041BDBVR and TPS2041BDBVT are high-quality power distribution switches from Texas Instruments, designed for USB applications where precision and reliability are paramount. These devices are part of the TPS2041B series, which are single-channel, current-limited, power-distribution switches optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Equipped with a 2.5V to 5.5V operating voltage range, these switches are capable of delivering an output current of up to 1A, making them suitable for a variety of USB peripherals. The TPS2041BDBVR and TPS2041BDBVT are designed to protect USB ports by integrating features such as over-current and short-circuit protection, thermal shutdown, under-voltage lockout, and controlled rise time to minimize current surges during turn-on.

The TPS2041BDBVR is available in a SOT-23-5 package, while the TPS2041BDBVT comes in a SOT-23-6 package. Both versions offer a fault report (over-current signaling) feature, which notifies the host when an over-current condition occurs. They also have an enable input that allows the host controller to turn the power switch on and off, providing further control over the connected USB devices.

These switches are characterized for operation over the free-air temperature range of -40°C to 85°C, making them suitable for various environments and applications. The TPS2041BDBVR/TPS2041BDBVT are designed to be compliant with USB 2.0 standards, ensuring compatibility with existing and future USB devices.

The compact size and robust protection features of the TPS2041BDBVR and TPS2041BDBVT make them ideal for a range of applications, including USB hubs, docking stations, and other peripherals requiring individual port power switching capabilities. With Texas Instruments' reputation for quality and performance, these power distribution switches are a reliable choice for managing USB power requirements in both commercial and industrial products.
