Copyright © 2012, Texas Instruments Incorporated TSU6111A SCDS331 – FEBRUARY 2012 www.ti.com DESCRIPTION The TSU6111A is a high performance differential autonomous SP2T switch with impedance detection. The switch supports the detection of various accessories that are attached through DP, DM, and ID. The charger detection satisfies USB charger specification v1.1 and VBUS_IN has a 28V tolerance to eliminate the need for external protection. Power for this device is supplied through VBAT of the system or through VBUS_IN when attached to a charger. The SP2T switch is controlled by the automatic detection logic or through manual configuration of the I2C. JIG and BOOT pins are used when a USB or UART JIG cable is used to test the device in the development and manufacturing. TSU6111A has open-drain JIG output (active low).

The type of accessory detected will be stored in I2C registers within the TSU6111A for retrieval by the host. The TSU6111A has a network of switches that are automatically opened and closed based on the accessory detection. See Table 1 for details of which switches are open during each mode of operation. The TSU6111A also offers a manual switching mode that allows the host processor to decide which switches should be opened and closed. The manual switching settings are executed through the I2C interface. STANDBY MODE Standby mode is the default mode upon power up and occurs when no accessory has been detected. During this mode, the VBUS and ID lines are continually monitored through comparators to determine when an accessory is inserted. Power consumption is minimal during standby mode. POWER SUPERVISOR TSU6111A uses VBAT as the primary supply voltage. VBUS is the secondary supply. VDDIO is used for I2C communication. Table 1.

If VBUS_IN is low and an accessory is attached, then use an ADC for impedance sensing on the ID pin to identify which accessory is attached. IMPEDANCE BUCKETS FOR EACH ACCESSORY In order to implement ID detection, each accessory should contain a ID impedance resistor value (refer toTable 2) which has a 5% tolerance accuracy. Table 2.

Once VBAT has reached VPOR, the reset condition is released, and the TSU6111A registers and I2C state machine initialize to their default states. After the initial power-up phase, VBAT must be lowered to below 0.2 V and then back up to the operating voltage (VDDIO) for a power-reset cycle. Software Reset The TSU6111A has software reset feature. • Hold low both I2C_SCL and I2C_SDA for more than 30ms to reset digital logic of the TSU6111A. After resetting the digital logic, INTB will keep low until INT_Mask bit of Control register (0x02) is cleared. Figure 1.

The SCL and SDA lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. I2C communication with this device is initiated by the master sending a START condition, a high-to-low transition on the SDA input/output while the SCL input is high (see Figure 2). After the start condition, the device address byte is sent, MSB first, including the data direction bit (R/W). This device does not respond to the general call address. After receiving the valid address byte, the device responds with an ACK, a low on the SDA input/output during the high of the ACK-related clock pulse. SDA SCL S P Start Condition Stop Condition Figure 2. Definition of Start and Stop Conditions The data byte follows the address ACK. The R/W bit is kept low for transfer from the master to the slave. The data byte is followed by an ACK sent from this device. Data is sent only if complete bytes are received and acknowledged. The output data is valid at time (tpv) after the low-to-high transition of SCL, during the clock cycle for the ACK. On the I2C bus, only one data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the high pulse of the clock period, as changes in the data line at this time are interpreted as control commands (START or STOP, see Figure 3). SDA SCL Data Line Charge Figure 3. Bit Transfer A Stop condition, a low-to-high transition on the SDA input/output while the SCL input is high, is sent by the master (see Figure 2). The number of data bytes transferred between the start and the stop conditions from transmitter to receiver is not limited. Each byte of eight bits is followed by one ACK bit. The transmitter must release the SDA line before the receiver can send an ACK bit. A slave receiver address must generate an ACK after the reception of each byte. The device that acknowledges has to pull down the SDA line during the ACK clock pulse so that the SDA line is stable low during the high pulse of the ACK-related clock period (see Figure 4). Setup and hold times must be taken into account. 12 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Link(s): TSU6111A TSU6111A SCDS331 – FEBRUARY 2012 www.ti.com Data Output by Transmitter NACK Data Output by Receiver ACK SCL From Master 1 2 8 9 Clock Pulse for Acknowledgment Start Condition Figure 4. Acknowledgment on I2C Bus Writes Data is transmitted to the TSU6111A by sending the device slave address and setting the LSB to a logic 0 (see Figure 5 for device address).

The command byte is sent after the address and determines which register is accessed. After a restart, the device slave address is sent again but, this time, the LSB is set to logic 1. Data from the register defined by the command byte then is sent by the TSU6111A. Data is clocked into the SDA output shift register on the rising edge of the ACK clock pulse (See Figure 7).

VBUS_IN, VDDIO, and VBAT require 1µF~10µF and 0.1µF decoupling capacitors to reduce noise from circuit elements. The capacitors act as a shunt to block off the noise. The 0.1µF capacitor smoothes out high frequencies and has a lower series inductance. The 1µF~10µF capacitors smoothes out the lower frequencies and has a much higher series inductance. Placing both capacitors will provide better load regulation across the frequency spectrum. 2. JIG is an open-drain output and therefore requires a 1kΩ ~ 10kΩ pull-up resistor to VBAT. 3. SCL and SDA require 1kΩ ~ 10kΩ pull-up resistors to VDDIO to prevent floating inputs. 4. VBUS_IN, DM_CON, and DP_CON are recommended to have an external resistor 2.2Ω to provide extra ballasting to protect the chip and internal circuitry. (a) For ID_CON, if there is less stress on the ID pin then the external 2.2Ω resistor is optional. 5. DM_CON, DP_CON, and ID_CON are recommended to have a 1pF external ESD Protection Diode rated for 8kV IEC protection to prevent failure in case of an 8kV IEC contact discharge. 6. VBUS_IN is recommended to have a 1pF ~ 10pF external ESD Protection Diode rated for 8kV IEC protection to prevent failure in case of an 8kV IEC contact discharge.

All the USB lines DP_CON, DM_CON, DP_HT, DM_HT, TxD, and RxD – Must have 45Ω single ended characteristic impedance – Must have 90Ω differential ended impedance – To fulfill USB 2.0 requirements 2. TSU6111A location – Close to the USB connector as possible – Keep the distance between the USB controller and the device less than 1 inch – Shortening the length of the trace will reduce effect of stray noise and radiate less EMI 3. Minimize use of VIAs for USB related signals – Differential transmission lines should be matched as close as possible – For optimum USB2.0 performance, use no VIAs DUT PAD DECOUPLING CAPACITORS 45 Degree Turns on USB signals MICRO USB CONNECTOR USB DP & DM lines length matched Place the USB connector as close as possible to the DUT 26 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Link(s): TSU6111A PACKAGE OPTION ADDENDUM www.ti.com 18-Feb-2012 PACKAGING INFORMATION Orderable Device TSU6111ARSVR Status (1) ACTIVE Package Type Package Drawing UQFN RSV Pins Package Qty 16 3000 Eco Plan (2) Green (RoHS & no Sb/Br) Lead/ Ball Finish MSL Peak Temp (3) Samples (Requires Login) CU NIPDAU Level-1-260C-UNLIM (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
