TSU6111
SCDS325 – SEPTEMBER 2011 www.ti.com SP2T Switch with Impedance Detection
Micro-USB Switch to Support USB, UART
Check for Samples: TSU6111 FEATURES APPLICATIONS VBUS_IN QFN-RSV PIN-OUT 16 15 14 13 DM_HOST 1 12 GND DP_HOST 2 11 SDA TxD 3 10 SCL RxD 4 9 INTB 5 6 7 8 VDDIO The switch is controlled by automatic detection logic
or through I2C manually. JIG and BOOT pins are
used when a USB, UART JIG cable is used to test in
the development and manufacturing. TSU6111 has
open-drain JIG output (active low). DM_CON Power for this device is supplied through VBAT of the
system or through VBUS_IN when attached. JIG The TSU6111 is a differential high performance
automated SP2T switch with impedance detection.
The switch features impedance detection which
supports the detection of various accessories that are
attached through DP, DM and ID. The charger
detection satisfies USB charger specification v1.1.
VBUS_IN has 28V tolerance to avoid external
protection. DP_CON DESCRIPTION BOOT Cell Phones and Smart Phones
