Maxim MAX77958 USB Type-C和USB供电控制方案

摘要: Maxim公司的MAX77958是单独可用的USB Type-C和USB供电控制器,采用Type-C CC检测和USB PD信息来检测连接附件或设备.器件能对过压和过流进行保护,并能检测USB Type-C连接器的湿度和防止腐蚀.器件还具有D+/D- USB开关和BC1.2检测,支持以前的USB标准.它还包含用于USB PD的VCONN开关,一个用于外接VCONN升压或降压转换器的使能引脚. MAX77958和USB Type-C标准Release 1.3和PD 3.0兼容,还很容易定制化而不影响兼容性.主要用在智能手机,平板电脑,照相机,游戏机,电源组,工业设备PoE到USB Type-C适配器,手持设备,手提设备,监视器,健康和医疗设备以及其它USB Type-C设备.本文介绍了MAX77958主要特性,框图,多种应用电路以及评估板MAX77958 EVK主要特性,电路图,材料清单和PCB设计图.
 The MAX77958 is a robust solution for USB Type-C CC detection and power delivery (PD) protocol implementation. It detects connected accessories or devices by using Type-C CC detection and USB PD messaging. The IC protects against overvoltage and overcurrent, and detects moisture and prevents corrosion on the USB Type-C connector. The IC also has a D+/D- USB switch and BC1.2 detection to support legacy USB standards. It contains VCONN switches for USB PD and an enable pin for an external VCONN boost or buck converter.

The IC is compliant with USB Type-C Specification Release 1.3 and PD 3.0. It can be customized easily without affecting the compliance.

The IC has an I2C master that can read and write to other device
