The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
The terms used in this application define:
a Micro Control Unit (MCU), also called a Single Chip Microcomputer (Single Chip Microcomputer) or a Single Chip Microcomputer (MCU), is used to reduce the frequency and specification of a Central Processing Unit (CPU).
The USB interface has three interfaces with different appearances, namely Type-A, Type-B, Type-C. Type-C has a much smaller volume than Tpe-A and Type-B, and is the latest USB interface appearance standard. In addition, Type-C is an interface Type that can be applied to both a PC (master device) and an external device (slave device, such as a mobile phone).
The USB Hub, refers to a device that can extend one USB interface to multiple interfaces and make these interfaces usable simultaneously. USB HUBs are classified into USB2.0HUB, USB3.0 HUB and USB3.1 HUB according to the USB protocol.
The PD protocol chip, namely the USB PD protocol chip, the communication of the PD protocol chip is a process of modulating the message of the protocol layer into a FSK signal of 24MHZ and coupling the FSK signal to the VBUS or obtaining the FSK signal from the VBUS to realize the communication between the mobile terminal and the charging adapter. In the USB PD protocol chip communication, 24MHz FSK is coupled to a DC level on VBUS through an cAC-Coupling capacitor, and in order to prevent the 24MHz FSK from influencing the VBUS DC voltage of PowerSuply or USBHost, a low-pass filter consisting of a zIsolation inductor is added in a loop to filter an FSK signal. The principle of the US BPD protocol chip, taking the case that both the mobile phone and the charger support the USB PD, is explained as follows:
1. the PHY of usb otg monitors VBUS voltage, and if VBUS voltage of 5V is present and it detects that the OTGID pin is a 1K pull-down resistor (not OTGHost mode, ID resistor of OTGHost mode is less than 1K), it indicates that the cable supports usb pd;
2. the USBOTG performs charger detection of a normal BCSV1.2 specification and starts the USBPD equipment strategy manager, the strategy manager monitors whether an FSK signal is coupled on a direct current level of VBUS, and decodes the message to obtain a capability source message, and the message is analyzed according to the USBPD specification to obtain all voltage and current list pairs supported by the USBPD charger;
3. the mobile phone selects a voltage and current pair from the capability source message according to the configuration of a user, adds the voltage and current pair to payload of the Request message, and then couples the FSK signal to the VBUS direct current level by the strategy manager;
4. the charger decodes the FSK signal and sends an Accept message to the mobile phone, and simultaneously adjusts the direct-current voltage and current output of PowerSupply;
5. the mobile phone receives the Accept message and adjusts the charging voltage and current of the charger IC;
6. the mobile phone can dynamically send a Request message to Request the charger to change the output voltage and current in the charging process, so that the process of the protocol chip is realized.
