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 ...

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 ...

Nexperia is aiming at protecting USB4 with a pair of semiconductor clamping chips – effectively back to beck Zeners, but built around active silicon-controlled rectification. “Since there are tight budgets on insertion loss and return loss for the USB4 Super Speed lines, Nexperia is offering devices that minimise the impact of ESD protection on the total budget,” said Nexperia product ...

CUI Devices has introduced a vertically-mounted power-only USB Type C connector. “By removing the data transfer pins, these USB Type C receptacles are a more cost-effective solution for designs where charging or power is the sole function,” according to the company. Called UJC-VP-3-SMT-TR, it joins the 60W UJC-HP-3-SMT-TR and 100W UJC-HP-G-SMT-TR horizontal-mount surface mount packages. It is a 6pin USB Type C receptacle ...

Check out this whitepaper covering how ON-Semi USB-C Programmable power supplies can tackle 5G smartphone fast charging demands. With the emergence of 5G technology, the telecommunications industry is taking significant strides in advancing wireless architectures. Despite the ever increasing capacity of Li-ion batteries, the rate of charging for these larger batteries is still improving. Read this whitepaper to see why. ...

Nexperia has managed to achieve 100fF load capacitance in devices designed to protect USB4 signal lines. “Of special interest to engineers designing USB4 and Thunderbolt interfaces, the new device uses Nexperia’s TrEOS ESD protection technology with active silicon-controlled rectification,” according to the firm. “It delivers a combination capacitance down to 0.1pF), dynamic resistance down to 0.1Ω and 20A 8/20µs surge robustness.” ...

Cypress Semi has announced a USB-C controller that supports PD 3.0 (power delivery) standard with PPS (programmable power supply) and Qualcomm’s QC 4.0 (quick charge) protocol. Dubbed CCG3PA, the chip is programmable via its ARM Cortex-M0 and 64kbyte flash with read-while-write for firmware upgrades. “As these standards and the USB Type-C standard continue to evolve, compliance and interoperability pose an ...

The first HDMI Alternate Mode cable, which allows phones, cameras and set-top boxes with USB-C video outputs to connect with HDMI port-equipped displays, including HD and 4K TVs

When Apple launched their super thin MacBook it decided to get rid of the bulky USB, Ethernet, HDMI, SD, VGA ports in one stroke. They were replaced with a single, thinner USB-C port. But what if you still need to connect USB, HDMI and Ethernet cables to your MacBook? US company Amango Mobile has come up with a portable adapter ...

Microchip has introduced a 16pin chip that can turn products with USB 2 and 3 ports into products with the new reversible USB-C connector. It is interposed between an existing circuit that had an old-style USB connector, and the USB-C connector replacing it. Called UTC2000, it handles the power and ancillary connections that surround USB-C, but not data signals which ...
