9V Fast Charging Protection Application with TS3USB3000

As the market moves towards faster charging methods, manufacturers require a higher input voltage at the power connector. A higher input voltage allows more power into the system for fast charging without increasing the current above the connector’s limited current-carrying ability. However, higher voltages increase the likelihood of damaging internal circuitry if there is a short circuit. Manufacturers with high design standards would generally opt to protect their internal circuitry from any possible damage. The TS3USB3000 USB switch can solve this problem by preventing the high voltages from reaching certain devices and hence protecting the devices.
