TI TPS65982
參考如下連結:
http://www.ti.com/product/TPS65982/datasheet
16.0 I2C Interface
The TPS65982 has three I2C interface ports. I2C Port 1 is comprised of the I2C_SDA1,
I2C_SCL1, and I2C_INT1 pins. I2C Port 2 is comprised of the I2C_SDA2, I2C_SCL2, and
I2C_INT2 pins. These interfaces provide general status information about the TPS65982, as
well as the ability to control the TPS65982 behavior, as well as providing information about
connections detected at the USB-C receptacle and supporting communications to/from a
connected device and/or cable supporting BMC USB-PD. The third port is comprised of the
DEBUG_CTL1 and DEBUG_CTL2 pins. This third port is always a master and has no
interrupt. This port is intended to master another device that has simple control based on mode
and mux orientation. The first two ports can be a master or a slave, but the default behavior is
to be a slave. Port 1 and Port 2 are interchangeable. Each port operates the same way and
has the same access in and out of the core. An interrupt mask is set for each that determines
what events are interrupted on that given port.

Description
The TPS65982 is a stand-alone USB Type-C & PD controller providing cable plug and orientation detection at the USB Type-C connector. Upon cable detection, the TPS65982 communicates on the CC wire using the USB Power Delivery (PD) protocol. When cable detection and USB PD negotiation are complete, the TPS65982 enables the appropriate power path and configures alternate mode settings for internal and (optional) external multiplexers.
The mixed-signal front end on the CC pins advertises 1.5 A or 3 A for Type-C power providers, detects a plug event and determines the USB Type-C cable orientation, and autonomously negotiates USB PD contracts by adhering to the specified bi-phase marked coding (BMC) and physical layer (PHY) protocol.
The port power switch can pass up to 3 A downstream at 5 V for legacy and Type-C USB power. An additional bidirectional switch path can provide USB PD power up to 3 A at a maximum of 20 V as either a provider (host), consumer (device), or provider-consumer.
The TPS65982 can also be a Downstream-Facing Port (DFP), Upstream-Facing Port (UFP), or Dual-Role Port (DRP) for data. The port data multiplexer can pass data to or from the top or bottom D+/D- signal pair at the port for USB 2.0 HS or UART and has a USB 2.0 Low Speed Endpoint. Additionally, the Sideband Use (SBU) signal pair is used for auxiliary or alternate modes of communication (DisplayPort or vendor-defined modes, for example).
The power management circuitry can utilize a 3.3-V or 5-V power supply inside the system, and also use VBUS to start up and negotiate power for a dead battery or no battery condition.
16.0 I2C Interface
The TPS65982 has three I2C interface ports. I2C Port 1 is comprised of the I2C_SDA1,
I2C_SCL1, and I2C_INT1 pins. I2C Port 2 is comprised of the I2C_SDA2, I2C_SCL2, and
I2C_INT2 pins. These interfaces provide general status information about the TPS65982, as
well as the ability to control the TPS65982 behavior, as well as providing information about
connections detected at the USB-C receptacle and supporting communications to/from a
connected device and/or cable supporting BMC USB-PD. The third port is comprised of the
DEBUG_CTL1 and DEBUG_CTL2 pins. This third port is always a master and has no
interrupt. This port is intended to master another device that has simple control based on mode
and mux orientation. The first two ports can be a master or a slave, but the default behavior is
to be a slave. Port 1 and Port 2 are interchangeable. Each port operates the same way and
has the same access in and out of the core. An interrupt mask is set for each that determines
what events are interrupted on that given port.

USB Power Delivery資料收集
USB PD主要目的在於訂定規範,利用USB Port 提供 Power 供Device 執行快速充電(統一目前所有Mobile Device充電方式),解決現有Device 充電方式及規格不一的窘境,基於環保及避免資源浪費.......
- Battery Charging Specification 1.2:[22] Released in December 2010.
Several changes and increasing limits including allowing 1.5 A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5 A and allowing a maximum current of 5 A. - Battery Charging Specification 1.1: Released in March 2007 and updated on 15 April 2009.
Adds support for dedicated chargers (power supplies with USB connectors), host chargers (USB hosts that can act as chargers) and the No Dead Battery provision, which allows devices to temporarily draw 100 mA current after they have been attached. If a USB device is connected to dedicated charger, maximum current drawn by the device may be as high as 1.8 A.

USB 3.1增加USB Power Delivery電力供應
USB 3.1也帶來新的電力供應規範 - USB Power Delivery（USB PD），設計上相容現有的USB 2.0和USB 3.0線材和連接器，新的USB 3.1 Type-C連接器也適用。USB PD支援更高的電壓和電流，以滿足不同的應用裝置，同時也相容現有的USB Battery Charging 1.2充電規格。USB PD為埠對埠的架構，USB和電力溝通訊號分開，電力的供應是透過主機端和裝置端的VBus通訊協定來溝通，如果裝置支援，則可依組態（Profiles）的電壓和電流，提供更高的瓦數供應。USB PD依裝置不同分成5個組態（Profiles），皆需要使用新的可偵測線材，才能提供大於1.5A或5V的電力。組態1針對手機，為5V/2A（10W），基本的電力輸出，已比USB 3.0的5V/0.9A（4.5W）還多； 組態2為5V/2A或12V/1.5A（最大18W），可為平板和筆電充電；組態3為5V/2A或12V/3A（可提供較大的筆電最大36W的電力）；組態4為最大為20V/3A（60W），但限制Micro-A／B連接器，組態5為最大為20V/5A（100W）的電力供應，但限TYPE-A／B連接器。PCDIY!認為USB 3.1供電的提升，以及支援充電的應用是非常重要的，這將會讓USB 3.1有望可以大一統手機、平板、電腦傳輸介面。

USB Power Delivery技術與架構詳解
USB Power Delivery (USB PD)在充電／供電規格上，制定了最基本的Profile 1 (提供5V@2A, 10W供電，適用於手機、數位相機等可攜裝置)、Profile 2 (提供5V@2A、12V@1.5A, 10～18W供電，適用於平板電腦、外接儲存裝置)、Profile 3 (提供5V@2A、12V@3A, 10~36W供電，適用於Ultrabook、變形平板等裝置)、Profile 4 (提供5V@2A、12/20V@3A, 10～60W供電，這是microUSB能支援的最大供電規格，適用於一般高效能筆電、AIO電腦)，以及最高級別Profile 5 (提供5V@2A、12/20V@5A, 10～100W供電，用於標準A/B與Type-C連接頭，可接液晶顯示器、平面電視)。

以下節錄自:
除“Battery Charging Revision 1.2”外，USB的規格每更新一次，供給電力都在增加。2012年7月亮相的“USB PD”實現了100W供電。預計支持產品將在2013年上半年亮相。
USB PD相應於供給電力分5級規格。以各規格確定電壓和電流供電。100W供電以20V電壓和5A電流實現（a）。USB PD的拓扑將供電側稱為“Provider”，受電側稱為“Consumer”（b）。（圖由《日經電子》根據USB PD的技術標准書制作）
“USB PD”首先辨別是否為支持線纜。接下來通過VBUS通信確定實際傳輸電力的電壓和電流。然后供電。這一連串動作由“Device Policy Manager”等管理部負責。（圖由《日經電子》根據USB PD的技術標准書制作）
USB PD與以往的USB規格不同，需要專用控制IC和專用線纜。控制IC被稱為“PD芯片”。專用線纜還可連接以往的USB連接器。（圖由《日經電子》根據USB PD的技術標准書制作）
註: Standard-A 母頭位於Host端, Device端若為PD Consumer,則會利用連接PD Provider端的PD detect端子偵測Host端是否為PD provider capability,因此具備PD Consumer能力的Device線材不同以往.......
USB PD Standard-A連接器為了辨別產品是否支持USB PD，在接收側的“插座”裡面新追加了“PD DETECT”端子。稍微加長了USB PD Standard-A插頭的長度，以接觸到PD DETECT端子（圖5）。通過檢測是否有接觸，來判斷是否為支持線纜。
“USB PD”的“Standard-A”連接器在接收側的插座中追加了用來檢測是否為USB PD支持線纜的“PDDETECT”端子（a、b）。該端子配置在插座裡面，僅長度較長的USB PD的Standard-A連接器能接觸到。（圖（a）由《日經電子》根據USB PD的技術標准書制作）
“USB PD”的“Standard-B”連接器追加了ID端子，用來判斷是否為支持線纜（a，b）。ID端子還用來確定流過線纜的電流值。根據電容器的安裝位置來判斷是3A用線纜還是5A用線纜（c）。（圖（a）由《日經電子》根據USB PD的技術標准書制作）
USB PD的Micro規格連接器方面，在原規格中設置了ID端子，因此沒有太大改變。不過，由於最大流過60W電力，連接器部和線纜部等容易發熱。Standard-A和Standard-B規格也同樣如此，USB PD的規格必須將溫度上升范圍控制在＋30℃以內。因此，必須採取不同於以往USB的熱對策。
追加PD芯片
關於USB PD新導入的確定電壓值和電流值的流程，通過在供電側和受電側雙方的產品中追加交換所需數據的IC、即“PD芯片”予以支持。通過在這兩個PD芯片間交換數據來確定發送的電壓和電流值。利用VBUS端子收發載流子頻率為23.2MHz、數據傳輸速度為300kbit/秒的“FSK（frequency shift keying）”信號。
美國英特爾公司的USB-IF人士介紹，PD芯片集成到USB控制器中的可能性比較低。這位人士認為因為“最合理又省錢的方法是，USB控制器利用現有的產品，USB PD隻在需要時追加PD芯片”。
