USB1T1102 • USB1T1102R (Preliminary)
Universal Serial Bus Peripheral Transceiver
with Voltage Regulator
General Description
This chip provides a USB Transceiver functionality with a
voltage regulator that is compliant to USB Specification
Rev 2.0. this integrated 5V to 3.3V regulator allows inter-
facing of USB Application specific devices with supply volt-
ages ranging from 1.65V to 3.6V with the physical layer of
Universal Serial Bus. It is capable of operating at 12Mbits/s
(full speed) data rates and hence is fully compliant to USB
Specification Rev 2.0. The Vbusmon pin allows for monitor-
ing the Vbus line.
The USB1T1102 also provides exceptional ESD protection
with 15kV contact HBM on D+, D− pins.
