Description The TCS2103 is a 16-mΩ current limiting power switch, integrated with the USB Type-C source controller and other proprietary charging methods. The TCS2103 monitors the Type-C Configuration Channel (CC) lines to determine when an USB device is attached. If a sink device is attached, the TCS2103 applies power to VBUS though the load switch. When the sink device is removed, the switch will be turned off and discharge the VBUS to safe voltage. Due to integrated auto-detect and auto-switch circuitry, the TCS2103 can apply correct electrical signatures automatically on the USB data lines to charge compliant devices among Apple, Samsung and BC1.2 DCP modes. The Apple 2.4/2.1A modes can also be configured. The TCS2103 provides accurate and programmable current limitation. When the output voltage is less than 4.0V or when an over temperature protection occurs during an overload condition, the TCS2103 enters hiccup modes. 4.
