Three new power control ICs drive tomorrow's one-cable world designs

Texas Instruments (TI) has introduced the first all-in-one USB Type-C and USB Power Delivery (PD) controller, which integrates a port power switch and port data multiplexer. The TPS65982 USB PD controller is the only integrated circuit (IC) available that provides the full power path, operating as a Single- or Dual-Role Port and enabling a variety of host and device power implementations, says the company. For applications requiring higher data rates, the TPS65982 can be combined with the 5.4Gbps HD3SS460, the industry’s first USB Type-C cross-point switch. This solution enables USB connectors on either end of the cable to be flipped up or down, delivers power up to 100W, and supports Alternate Modes to distribute video over DisplayPort from the host to the end device. For USB Type-C systems requiring up to 15W of power, engineers can choose the TUSB320 family, the industry’s first devices to provide USB Type-C configuration channel (CC) logic and port control. These devices make it possible for a system to detect the orientation of the plug, and determine the appropriate USB specification and mode settings for the end equipment. The USB (Universal Serial Bus) interface standard is popular in smartphones and other personal electronics, as well as computers and peripherals such as printers. Using TI’s new USB Type-C products, designers can deliver end equipment that frees consumers from needing multiple cables for various types of USB ports. Each of the new TI devices meets USB Type-C Specification 1.1 (Engineering Change Notice as of June 22, 2015) published by the USB Implementers Forum (USB-IF), of which TI is a long-standing participant. TI has a more than 20-year track record of providing high-performance USB-compliant products. Key features : 1 - Single USB PD controller delivers power and data in multiple modes: The TPS65982 integrated PD controller and power switch delivers both power and data in several Alternate Modes. The TPS65982 can operate as a Single- or Dual-Role Port (DRP) for power and can be configured to support data as a downstream-facing port (DFP); an upstream-facing port (UFP); or as both host and device, known as a DRP. 2 - SuperSpeed switch transfers video data at low power: The HD3SS460 USB Type-C cross-point switch can support data rates up to 5.4 Gbps while offering standby power of 40 µW – more than 50 percent lower than competitive offerings – to extend battery life. 3 - USB Type-C CC logic: The TUSB320 family supports USB 2.0, USB 3.1 and VCONN, giving designers the flexibility to use these devices in multiple USB-enabled designs. Its low shutdown power of 8mW benefits a variety of battery-powered applications. The TPS65982 is available in a 6-by-6-mm MicroStar Junior ball-grid array (BGA) package. The HD3SS460 is available in a 3.5mm x 5.5mm quad flat no-lead (QFN) package and the TUSB320 is available in a 1.6mm x 1.6mm QFN package. Engineers can speed up their USB Type-C system designs with evaluation modules (EVMs), including the TPS65982-EVM (includes BoosterPack pin standard for TI’s low-cost LaunchPad ecosystem), the HD3SS460EVM-SRC and the TUSB320EVM. Designers can jump-start their design with the USB Type-C Dock reference design (TIDA-00630). Engineers designing with USB Type-C can also search for solutions, get help, share knowledge, and solve problems with fellow engineers and TI experts in the TI E2ETM Community USB forum.
