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 V external protection. Power for this device is supplied through VBAT of the system or through V 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).

GENERAL OPERATION

The TSU6111A will automatically detect accessories plugged into the phone via the mini/micro USB 5 pin connector. 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.
