New Family of USB Power Delivery Controllers from Microchip

June 19, 2014

PR_UPD1001-7x5Finally Microchip announces the first device of a new family of USB Power Delivery Controllers, the UPD1001.

The new device is a highly flexible and configurable solution that supports the 5 USB-IF standard UPD power profiles plus an additional 25 UPD-compliant profiles for a total of 30 profiles supported by a single chip. This will allow designers to select the optimum power profiles in order to meet their specific application requirements.

Pro’s

  • Support 5 defined USBPD power profiles + 25 additional user’s defined profiles
  • Fully integrated. Microprocessor and USBPD controller
  • Offering integrated ADC for Voltage/current  monitoring
  • Coming with a ready-to-use UPD1001 Evaluation Kit (part # EVB-UPD100).  It integrates everything you need for a USB Power Delivery provider.
  • Delivered in Consumer (0°C to +70°C),  Industrial (-40°C to +85°C) and Automotive  (-40°C to +105°C) grade

Con’s

  • Only provider, meaning not supporting  swap features. Looking at the published UPD100x family roadmap, we should wait for the UPD1002 to have the role swap available.
  • Compliant with USBPD v1.2. We are currently at v1.3
  • Not clear the level of flexibility and programmability

USB Power Delivery: looking for a tester?

March 6, 2014

I attended the USB Power Delivery Interoperability event in Portland on middle of Jan. The opportunity was to test the CT20600 USB-PD complete solution from Canova Tech.

During the test sessions, I had the opportunity to touch the new USB test solution from Ellisys, a worldwide leader in protocol test and analysis solutions. The USB Explorer 350, just announced in the company news,  is intended for technology developers working on products employing features specified in the recently released USB Power Delivery specification.

Ellisys EX350

Waiting for the USB Power Delivery compliance procedures delivery from usb.org, the USB Explorer 350 could be a valid and powerful instrumentation helping developers to characterize protocol compliance of silicon, software, and systems and to verify corner case communications. The device can be configured to play as a protocol analyze by sniffing the communication between two USB-PD devices or as emulator (producer or consumer).

It comes with a powerful software GUI that enable a complete monitor, analysis and control of the communication protocol. For a detailed description and list of features, please check product page.

A USB-PD Analyzer and Emulator is a great tool for developers and designer to test their products and to be ready for final product qualification and compliance tests. The Ellisys  USB Explorer 350 is the first solution in the market, most probably not the only one in the short term. I’ll check the web for other solutions and/or similar products.

Is the USB Power Delivery a Game Changer?

October 28, 2013

The first USB PD devices will come to market in 2014, with a “big roll-out” in 2015, says Brad Saunders of Intel. Gregory Reed, of the Swanson School of Engineering at the University of Pittsburgh, calls the new USB standard a “game-changer”.

This is an extract of an interesting article from The Economist related to the USB Power Delivery: The humble USB cable is part of an electrical revolution. It will make power supplies greener and cheaper.

Anyone interested on USB-PD and in general on new technology should read.

USB Recharge port on HP Chromebook 11: One port to rule them all

October 14, 2013

A newborn  just enter entered in the always growing family of Chromebook devices: the HP Chromebook 11.

ht_chromebook_google_16x9_992

What captured my attention is the unusual charge solution: not anymore hp-chromebook-11-micro-usba dedicated jack to connect an external charger, but a microUSB, as described by JR Raphael in his review. Like our portable devices, smartphones or tabled. This is a great news in my perspective, at least for two reasons.

Standardization

It is the first step to standardize the recharger mechanism: no more custom and proprietary jacks and charger, but an universal main adapter with USB connection compatible with all our device, hopefully with more then one USB port to recharge many device at a time. One Ring to rule them all. This will impact the final price of the device, too.

Power Flexibility

A single connector will simplify our life. But soon users will ask to have more flexibility. To recharge batteries in a faster mode delivering more power and to use this port to recharge portable device as well, or to supply external peripherals. In one word, USB Power Delivery technology. Able to deliver up to 100w over USB cable.

Dreaming

This device is the first step in the direction of simplifying our life among different and proprietary chargers, jacks and connectors. I hope to see more device implementing this bold solution with a step forward toward USB power delivery and more peripherals and devices taking advantage from this technology.

USB Power Delivery at the Intel IDF13 in San Francisco

September 30, 2013

I attended in San Francisco the Intel Development Forum 2013 (IDF13).

My interest was obviously for the USB Power Delivery and my target was to establish new contacts with the USB-PD players and to collect information of new or incoming products.

The Most Promising Technologies for Super Fast Charging

September 27, 2013

The dream of any user of mobile devices is to have its batteries always charged. The second is to have the possibility to charge the batteries as fast as possible, while preserving battery life.

battery-charge-icon1-300x185

While the identification and introduction of new battery technologies is a complex innovation process with a long time to market, a big effort is spent to define and impose new ways to deliver more power in charging mode, making the life of the user more and more easier.

This approach involves the definition and adoption of new standards based on common and shared specifications and it involves the creation of a new ecosystem of connectors, cables, chargers, adapters and semiconductor solutions. The time to market in this case is much faster and new solutions are popping-up in the last year.

The most promising alternatives are:

  • Wireless Charging
  • USB Power Delivery
  • Qualcomm Quick Charge

USB Power Delivery Showcase from INTEL

July 11, 2013

At the Technology Showcase at IDF Beijing, INTEL demonstrated a typical application of the USB Power Delivery feature: a portable PC delivering through a USB2.0 connection video streaming at 480Mbit/s (not really a big deal) and at the same time the power to supply a LCD monitor.
