Copyright © 2013, Texas Instruments Incorporated TSU6721 SCDS338B – JANUARY 2013 – REVISED JUNE 2013 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. DESCRIPTION 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. 2 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links :TSU6721 TSU6721 www.ti.com SCDS338B – JANUARY 2013 – REVISED JUNE 2013 BLOCK DIAGRAM VDDIO I2C Interface SCL Switch Ctrl SDA Load Switch Sense & Ctrl.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.
