N.C. – Not internally connected

D+, D–, and ID pins are exact equivalent

ESD clamp circuits. Any of these pins can

be connected to any other D+, D–, or ID

pin if it becomes easier to route the traces

from the USB connector.

DESCRIPTION

The TPD4S012 is

four-channel electrostatic

–

Â±10-kV IEC 61000-4-2 Contact Discharge

Â±10-kV IEC 61000-4-2 Air-Gap Discharge

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 TPD4S012

offers combinations of two different clamp voltages to

match the voltage tolerances of the different signal

interfaces using the common USB connector. Refer

to Figure 5-6 & Figure 9-12, special snap back

technology allows high-voltage tolerance during

normal operation while reducing the clamp voltage

during system level ESD stress.

•

3 Amps Peak Pulse Current (8/20 μs Pulse) for

V_BUSand D+, D–, and ID Lines

Industrial Temperature Range: –40°C to 85°C

APPLICATIONS

•

Cellular Phones

Digital Cameras

Global Positioning Systems (GPS)

Portable Digital Assistants (PDA)

Portable Computers

The TPD4S012 conforms to IEC61000-4-2 (Level 4)

ESD. The device is offered in space-saving packages

with flow-through pin mapping.

The TPD4S012 is characterized for operation over

ambient air temperature of –40°C to 85°C.
