TSU6721 is a high performance USB port multimedia switch featuring automatic switching and accessory detection. The device connects a common USB port to pass audio, USB data, charging, On The Go (OTG) and factory mode signals. The audio path has negative signal capability includes left (mono/stereo), right (stereo) as well as microphone signals. Furthermore, TSU6721 is compatible with the MCPC specification.
TSU6721 features impedance detection which supports the detection of various accessories that are attached through DP, DM and ID pins of the USB connector. The switch is controlled by automatic switching or manually through I2C.
TSU6721 has an integrated low resistive Load Switch that is used to isolate the charger from the external connector. OverVoltage Protection and programmable OverCurrent Limiter/Protection are additional features included to the Load Switch.
The charger detection satisfies USB charger specification v1.2. In addition to DCP, CDP and SDP, the device also detects Apple Chargers.
Power for this device is supplied through VBAT of the system or through VBUS when attached. TSU6721 supports factory mode testing when a USB/UART JIG cable is used in development and manufacturing.
