4-CHANNEL ESD SOLUTION FOR USB-HS/USB
OTG/USB CHARGER INTERFACE
The UTC USB4S012 is a four-channel electrostatic discharge
(ESD) solution for USB charger or USB on-the-go (OTG) interface.
In many cell phone applications, the USB connector is the de facto
communication port for external communications like high-speed
data transfer, audio signal, charging, car-kit, etc. In order to support
different interfaces, the USB port needs to handle different voltage
levels. For example, some chargers require the VBUS port of the
USB connector to handle in excess of the normal VBUS voltage per
USB specifications. The UTC USB4S012 offers combinations of
two different clamp voltages to match the voltage tolerances of the
different signal interfaces using the common USB connector.
The UTC USB4S012 conforms to IEC61000-4-2 (Level 4) ESD.
The device is offered in space-saving packages with flow-through
