TUSB320: A device that provides USB C-type configuration channel logic and port control

Most of us have become very dependent on mobile phones that keep in touch with professionals, family and friends. However, there is a place where the author feels the most difficult to keep in touch with the outside world - where? It’s in your own car. The author's phone is placed in the passenger seat, receiving new text messages, emails, social media notifications, and recording missed calls. When I encounter a red light, I often grab the phone and quickly check the new notification. But when I arrive at my destination, the battery power of the phone is usually running low.

I tried all Bluetooth® products and 12V mobile phone chargers. Whenever I buy a new product, I am excited to be excited for a while, but it will soon be unable to meet the demand. When I use the speakers in my car, people complain that the voice quality is not good; and the author's mobile phone (which functions almost no less than a laptop) can barely maintain the state of charge, never approaching 500mA. Charging. In addition, audio content can't reach the car and be shared on its many powerful displays.

However, when I work with the Universal Serial Bus (USB) C-type port, I can change the driving experience. (In fact, I always wanted to wait for someone to let the USB C-type port fully realize its potential in the automotive field. I am very excited about the way my current car discount is replaced by a new car that can realize the experience. The USB Type-C port will easily provide 15W of charging power (up to 100W with USB Power Delivery specification) and 20Gbps data transfer rate; even the author's mobile phone must go all out to fill the Transmission line. This makes the author passionate about the heart of electronic products. I may have to upgrade my phone (or at least its memory), please don't tell the author's wife. On the other hand, if you have a good news, please be sure to tell her - this feature will allow all passengers to enjoy the best features of their mobile phone while traveling in the author's car. In addition, sharing social media posts with the entire family will also become easier.

As a device that provides USB C-type configuration channel logic and port control, the TUSB320 enables this experience and is now available. The device manages all USB C-Channel Controllers (CCs) and mode configuration communications for USB 2.0.

The TUSB320, TUSB321, HD3SS3212 and HD3SS460 are available as a commodity, and most devices are Q100 certified. It is really fascinating to think that the author's next car can have these functions.

Are you ready to take full advantage of your phone's features in your car and fully charge your phone when you arrive at your destination?
