7 Detailed Description

7.1 Overview

The TPD6F002 is a highly-integrated ESD protection and EMI filtering device intended for use where small size

and ease of routing are important. Common applications include LCD display interfaces, memory interfaces,

GPIO lines, and FPD-Link.

7.3 Feature Description

7.3.1 Six-Channel EMI Filtering

This device provides six channels for EMI filtering of data lines with the following parameters:

•

–57-dB Crosstalk Attenuation at 100 MHz

•

–35-dB Insertion Loss at 800 MHz

•

–3-dB Bandwidth at 100 MHz

7.3.2 Pi-Style Filter Configuration

This device has a pi-style filtering configuration composed of a series resistor and two capacitors in parallel with

the I/O pins. The typical resistor value is 100

Ω and the typical capacitor values are 17 pF each.

7.3.3 Robust ESD Protection

The ESD protection on all pins exceeds the IEC 61000-4-2 level 4 standard. Contact ESD is rated at ±20 kV and

Air-gap ESD is rated at ±30 kV.

7.3.4 Low Leakage Current

The I/O pins feature an ultra-low leakage current of 20 nA (maximum) with a bias of 3.3 V

7.3.5 Space-Saving WSON Package

The layout of this device makes it easy to add protection to existing layouts. The packages offer flow-through

routing which requires minimal changes to existing layout for addition of these devices. Additionally, the device

offers a small, space-saving package that takes a minimal footprint on the board.

7.4 Device Functional Modes

The TPD6F002 is a passive integrated circuit that passively filters EMI and triggers when voltages are above VBR

or below the lower diode voltage (–0.6 V). During ESD events, voltages as high as ±30 kV (air) can be directed

to ground through the internal diode network. Once the voltages on the protected line fall below the trigger levels,

the device reverts to passive.
