TPS2064CDGN-2 USB Power Distribution Switch

The TPS2064CDGN-2 is a high-quality USB power distribution switch from Texas Instruments, designed for applications where heavy capacitive loads and short circuits are likely to be encountered. This integrated circuit provides 1.5A of continuous current across all four channels, with each channel being individually controlled.

This robust device is housed in an 8-pin MSOP (DGK) package, making it suitable for space-constrained applications. The TPS2064CDGN-2 features multiple safety mechanisms, including over-current protection, over-temperature protection, and under-voltage lockout, ensuring reliable operation under adverse conditions. It also boasts a fast over-current response time, typically just 2μs, which helps to protect downstream circuitry from damage.

The TPS2064CDGN-2 offers a wide operating voltage range of 2.7V to 5.5V, making it versatile for various USB-powered devices. Its low on-resistance of typically 70mΩ per channel minimizes power loss and heat generation, contributing to the overall efficiency of the system it is integrated into.

Another notable feature of this power switch is its built-in charge pump, which limits the need for external components. The charge pump allows the TPS2064CDGN-2 to maintain output voltage without a significant drop, even at full load. Additionally, the device supports continuous heavy load conditions, making it ideal for bus-powered peripherals, docking stations, and monitors.

For designers and engineers looking for a reliable power management solution, the TPS2064CDGN-2 is an excellent choice due to its performance, safety features, and Texas Instruments' reputation for quality in the semiconductor industry.
