4-CHANNEL ESD SOLUTION

FOR USB-HS/USB OTG/USB

CHARGER INTERFACE



DESCRIPTION

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 V_BUSport of the

USB connector to handle in excess of the normal V_BUSvoltage 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

pin mapping.
