它是如何工作的?

USB-C Power Click基于TPS25750S,这是一款来自德州仪器的USB Type-C和电源传输(PD)控制器,提供单个USB Type-C连接器的电缆插入和方向检测。TPS25750S在检测到电缆时通过CC线使用USB PD协议进行通信。当电缆检测和USB PD协商完成后,TPS25750S根据设定的配置启用适当的电源路径,以在USB IN-OUT连接器上提供或接收电源。TPS25750S针对支持USB-C PD电源的应用进行了高度优化,提供了强大的保护和完全管理的内部电源路径(5V/3A,36mΩ源开关)。第二个USB连接器标记为5V IN,用于以USB连接形式提供5V电压,这是内部5V源电源路径所必需的。此Click板™通过标准I2C 2线接口与MCU通信,以读取数据和配置设置,最大频率为

400kHz。此外,它还具有一个额外的中断信号,连接到mikroBUS™插座的IRQ引脚。除了用于与主机MCU通信的I2C端口外,TPS25750S还具有一个最大频率为400kHz的主配置I2C接口,可以连接到电池充电器(如BQ25792)或外部EEPROM,以传达适当的配置以设置充电模式、充电电流、OTG模式等。BQ25792是一款适用于1-4节锂离子和锂聚合物电池的全集成开关模式升降压充电器,允许用户以高达3A的功率源或接收电源。与电池充电器通信所需的电源和线路位于板右侧的未填充引脚上。得益于板载ADC跳线,TPS25750S可以根据位置设置死电池配置和PD控制器的I2C从设备地址。提供的两种死电池配置是安全模式和始终启用接收模式。安全模式不启用接收路径,并且在加载

配置之前禁用USB PD。在始终启用接收模式下,无论连接的源提供的电流量如何,设备都会启用接收路径。在加载配置之前,USB PD被禁用。此Click板™还具有两个位于未填充引脚上的GPIO信号,用于状态和控制信息的用户定义。GPIO引脚可以映射到USB Type-C、USB PD和特定应用事件,以控制其他IC、中断主处理器或接收来自其他IC的输入。除了GPIO,它还具有两个LED指示灯,IO0和IO1,用于在操作期间实现一些异常或状态的视觉检测。此Click板™只能在3.3V逻辑电压水平下运行。使用不同逻辑电平的MCU之前,必须进行适当的逻辑电压电平转换。此外,该Click板™配备了包含功能和示例代码的库,可用作进一步开发的参考。

/*!
 * @file main.c
 * @brief USB-C Power Click example
 *
 * # Description
 * This example demonstrates the use of the USB-C Power Click board™
 * by configuring the PD controller to attempt to become a Power Source.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module, log UART, and additional pins.
 * After the driver init, the app executes a default configuration,
 * depending on PD Device Mode, the app performs the patch bundle update tasks
 * for loading a patch bundle in burst mode to the PD controller.
 *
 * ## Application Task
 * The application display status information about 
 * the PD controller data role and power of the connection.
 * Results are being sent to the UART Terminal, where you can track their changes.
 * 
 * ## Additional Function
 * - static void usbcpower_display_status ( void )
 * - static void usbcpower_display_pwr_status ( void )
 *
 * @note
 * For the advanced configuration, use the TPS25750 Application Customization Tool:
 * https://dev.ti.com/gallery/search/TPS25750_Application_Customization_Tool
