Communication interface chip UART485/232

The FUSB301 is a fully autonomous Type-C controller optimized for <15 W applications. The FUSB301 provides source current mode, sink current mode, dual role port mode, accessory detection support, and constant current logic detection for battery drain support. The FUSB301 has an external switch pin (SS_SW) that provides external USB SuperSpeed ​​switching without interrupting the processor. The FUSB301 has a very low power disable mode as well as a low power mode during normal operation. The device features an ultra-thin 10-pin TMLP encapsulation.

RS-232 serial port single power level conversion chip, +5v single power supply.
