Pizza and Lecture: USB Fast Charging
The Universal Serial Bus has become ubiquitous since its inception in 1996. Not only is it used to transmit many kinds of data, but this interface has become the standard for charging and powering nearly every kind of electronic appliance. The original standard only supported delivering 2.5W of power, but the latest standard: Power Delivery (USB-PD) can support the bidirectional delivery of up to 100 Watts. There is a lot more going on behind that charging socket in your car than there used to be. This talk will cover the new USB power standards by reviewing the evolution of the standard from type-A to type-C to type-PD. We will review the handshake protocols that occurs between your phone and a USB charging socket for type-A, type-C and type-PD. Finally, some example circuits will be presented showing real-world design trade-offs.
