Alpha and Omega Semiconductor has released a 7A 23V USB Type-C protection and reverse-blocking switch IC. Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates ...

USB Type-C connector gets rugged MIL-DTL-38999 treatment
Amphenol has introduced a rugged USB Type-C connector for harsh environments. Called USB3CFTV, its tough exterior is based on MIL-DTL-38999 series III, in shell size 11. Its tri-start thread coupling is designed to resist shocks (IK06 mated pair), vibration and cable traction, and the casing seals against fluids and dust to IP68. Expected life is at least 500 mating cycles. ...
10Gbit/s USB peripheral controller
Infineon has created a 10Gbit/s USB peripheral controller, intended to be used in devices that connect to a host via USB-C. Called CYUSB4014-BZXI, it has an Arm Cortex-M4 processing core, a Cortex-M0+, 1,024kbyte of ram and 512kbyte of flash. Alongside USB-C, it has LVDS, LVCMOS and QSPI serial interfaces, and a crypto processor. This is actually one of four in ...
Software converts STM32G0 MCU to UCSI USB Type-C PPM
STMicroelectronics has released software to make its STM32G0 32bit Cortex-M0+ microcontroller into a UCSI ‘platform policy manager’ (PPM) to manage USB Type-C connectors – in particular for its STM32MP135F-DK development board. UCSI is the USB Type-C connector system software interface, controlled by a specification from the USB Implementers Forum. The software, ‘X-CUBE-UCSI expansion package’, consists of libraries, drivers, sources, APIs ...
IC handles USB-PD up to 100W
For GaN-based power adaptors with USB-PD outputs, STMicroelectronics has announced an active clamp fly-back controller with a USB-PD 3.1 interface in a single package, that includes galvanic isolation between primary and secondary sides, crossed by a data link. Called ST-OneMP, on its primary side, it is designed to work with one of the company’s GaN half-bridge-plus-driver combo ICs, communicating through ...
Libraries link STM32 USB PD peripheral to UBS port protection ICs
STMicroelectronics has released C libraries to control its three USB Type-C Power Delivery port-protection ICs, for sink or source applications, or both. The code will run on certain of the company’s STM32 microcontrollers, which have the company’s ‘UCPD’ interface, for which the company has development boards. The UCPD interface, together with one of the protection ICs and the code, can ...
USB4 v2.0 offers 80Gbit/s through USB Type-C cables
USB Promoter Group has announced USB4 Version 2.0, which will enable up to 80Gbit/s through USB Type-C cables and connectors. The associated specification is due before USB DevDays in November. It will deliver “up to 80Gbit/s operation based on a new physical layer architecture, using existing 40Gbit/s USB Type-C passive cables and newly-defined 80Gbit/s USB Type-C active cables”, according to ...
Rugged waterproof USB 2.0 Type-C connector
Hirose has created a waterproof USB 2.0 Type-C connector. The IP8x-rated CX90MW6 (lower in image) meets requirements for immersion in 1.5m of water for 30 minutes. It is mid-mount, partially loosing its height in the thickness of the PCB, and screw-mounted to the PCB. A front sealing gasket prevents water penetration into the shell, while potting prevents water intrusion into ...
Power Integrations aims at 135W – 200W USB PC adapters
Power Integrations is aiming at 135W USB-C power delivery adapters using a zero-voltage switching fly-back converter IC and partner primary-side active-clamp IC. “The use of a non-complementary-mode active clamp enables designs that work in both continuous and discontinuous modes,” said company marketing manager Edward Ong”. “By operating across modes, it is much easier to support the wide load range conditions ...
Rugged USB Type-C connectors
Bulgin has added USB Type-C 3.2 Gen 2×2 connector options to its Buccaneer range of robust connectors. The 4000 Series connectors have a USB-C 2×12 contact arrangement and can support 20Gbit/s (1m length cable USB3.2 Gen 2×2, 10Gbit/s over 2m cable). Power rating is 100W, in line with Type-C Power Delivery specs. Mating endurance is 1,000 cycles and operational is over ...
