TPD4S012 具有电源钳位的 4 通道 USB ESD 解决方案
The TPD4S012 is a four-channel electrostatic discharge (ESD) solution for USB charger or USB on-the-go (OTG) interface. In many cell phone applications, the USB connector is the de facto communication port for external communications like high-speed data transfer, audio signal, charging, car-kit, etc. In order to support different interfaces, the USB port needs to handle different voltage levels. For example, some chargers require the VBUS port of the USB connector to handle in excess of the normal VBUS voltage per USB specifications. The TPD4S012 offers combinations of two different clamp voltages to match the voltage tolerances of the different signal interfaces using the common USB connector. Refer to Figure 5-6 & Figure 9-12, special snap back technology allows high-voltage tolerance during normal operation while reducing the clamp voltage during system level ESD stress.
