 In this e-presentation, we'll review why and how to protect USB Type-C connectors against overvoltage and ESD. So first, we'll describe the new USB Type-C connector and review the protection requirements, and then we'll present the TCPP01-M12 protection for USB Type-C connectors and review the associated electronic applications. Let's start with the new USB Type-C connector. The USB Type-C connector is replacing all legacy USB connectors. Many PCs and smartphones nowadays use a USB Type-C connector, and this connector is now appearing in mass market and consumer, industrial and automotive applications. The new USB Type-C connector features a slim and sleek connector tailored to fit mobile device product designs, yet robust enough for laptops and tablets, reversible plug orientation and cable direction, and it also supports scalable power and performance to future-proof your solution. The market is migrating from legacy USB Type-A-B connectors to new USB Type-C connectors with the following key features. You can flip the plug within the connector, and you can also flip the cable itself just like your Apple Lightning connector. The end user doesn't have to worry about the data or power direction. This makes the users life easier as they no longer need to try to plug in the cable two or three times before it goes in. Also, this new connector can support the power delivery protocol to accelerate the charging speed of battery-operated devices. With the alternate mode, the USB-C connector can be used to transmit videos using DisplayPort or Thunderbolt. With all these features, the end user's life is simplified, but the designer's life is definitely becoming more complex because we are moving from a legacy connector to a 24-pin connector. Also, the power role, meaning which connector is supplying the current and which one is receiving it, used to be mechanically defined. The source supplying the current used to be a Type-A connector and the sync, the one receiving the current, used to be a Micro-B connector. But now, seeing as the Type-C connector is reversible, the application can be sync or source. The power role is now defined electronically by the configuration channel pins CC1 and CC2 pins. Also, with legacy Type-A or Micro-B connectors, the USB power supply was typically 5 volts. Whereas with USB Type-C, the designer can choose to stay at 5 volts or take advantage of the power delivery protocol that allows up to 20 volts voltage on Vbus to accelerate the charging speed of battery-operated devices. Amidst the complex implementation of USB Type-C electronics, specific care must be taken to avoid many issues related to overvoltages and ESD. When migrating from Type-A or B to USB Type-C, three issues can appear. One, electrostatic discharge because the metallic connector is an entry point for ESD. Two, defective power adapter. Three, configuration channel pin shorted to Vbus. The metallic pins of the USB-C connector are an entry path to electrical static discharge or ESD. This can cause reliability issues or even destroy integrated circuits present in the PCB. This ESD is rated as per IEC 61000-4-2 with plus or minus 8 kV in contact discharge. The only way to protect against IEC ESD discharge is to implement an ESD protection rated for this standard. Otherwise, ICS will fail in various electrical overstress or EOS mode like melting flash. A defective adapter or cable can deliver a voltage higher than expected. In this example, the charger delivers 20 volts without negotiation with the sink. There have been many issues in the past due to poor quality cables or adapters as can be seen on different YouTube videos if you check around. The USB Type-C connector pitch has been reduced from 0.65 mm in USB Type-AB to 0.5 mm in USB Type-C. There is more of a risk of shorting data lines to the power line in the connector when the user plugs or unplugged the USB-C cable. Now let's review the features and benefits of the TCPP01-M12 ST Microelectronics Type-C port protection. The TCPP01-M12 fits all sink or source applications. The core market for TCPP01-M12 is sink applications, i.e. all applications requiring power to function, like e-cigarette, smart speaker, power tools, etc. ST Microelectronics TCPP01-M12 protects USB Type-C applications against ESD and overvoltage on VBUS and CC lines thanks to high voltage technology. TCPP01-M12 key features covers the top three electrical issues with USB-C cables. 1. ESD protection on CC and VBUS lines. 2. Protection against CC line short to VBUS thanks to integrated overvoltage protection. 3. Overvoltage protection on VBUS thanks to integrated gate driver for an external end-channel MOSFET. On top of its protection features, TCPP01-M12 also integrates dead battery resistors on both CC lines, disconnected by MCU at power-up. Is compliant with the latest USB Type-C power delivery specification. Includes the new PPS mode, allowing quick charging for batteries up to 20 volts thanks to programmable power supply mode. The key benefits of the TCPP01-M12 key are 1. Protection against the top three electrical issues with USB-C connector. 2. Null power consumption for sync applications when no cable is attached. 3. Cost competitive optimum solution for sync mass market applications minimizing bomb count and cost. Also, it is the companionship of the STM32 with an integrated USB Type-C controller with the STM32 acting as a power delivery controller. The associated firmware is available with STM32-Cube MX monitor. Now let's check out some application examples with TCPP01-M12. Moving to use USB Type-C only offers customers the capacity to use up to 15 watts from a USB source. Moving to USB-C power delivery offers customers the capacity to use up to 100 watts from a USB source. To move from USB Type-C only to USB-C power delivery, the bomb change is very minor thanks to TCPP01-M12 versatility and compliancy with all STM32 and STM8 microcontrollers. USB Type-C power delivery advantages are at a low cost and low risk for the customers. Here is an example of how the TCPP01-M12 works with an STM32 USB-C PD example. The XNUCLEO boards enable customers to evaluate the TCPP01-M12 for a USB-C PD use case with STM32-G0 and STM32-G4. To summarize, the TCPP01-M12 enables safe, efficient and low cost migration to a USB Type-C connector thanks to overvoltage protection against a defective power adapter, integrated gate driver for N-channel MOSFET. Up to 80% PCB space reduction compared to an equivalent discrete solution thanks to QFN12 3.0mm x 3.0mm. And there is no need for an external USB-C power delivery controller when used with STM32-G0 G4 L5. For more information on the TCPP01-M12, please check out the datasheet on ST.com.
