4-Line EMI Filter with Integrated ESD Protection

General Description

Features

The AOZ8014 is an 4-line device integrating EMI ﬁltering

with ESD protection for each line. It is designed to

suppress unwanted EMI/RFI signals and provide electro-

static discharge (ESD) protection in portable electronic

equipment. This state-of-the-art device utilizes AOS

● 4 lines for EMI ﬁltering and ESD protection:

– Exceeds IEC 61000-4-2, level 4 (ESD) immunity test

– ±17kV (air discharge) and ±17kV (contact discharge)

● Trench Vertical Structure [TVS] ™ based technology

used to achieve excellent ESD clamping & ﬁlter

performance over the full operating display range

leading edge Trench Vertical Structure [TVS] ™

technology for superior clamping performance and ﬁlter

attenuation over the full operating display range. The

AOZ8014 has been optimized for protection of color LCD

displays and CCD camera lines in cellular phones and

other portable consumer electronic devices.

● Filter performance: -25db attenuation from 800MHz to

3.0GHz

● Low operating voltage: 5.0V

● Capacitance stability over wide range of voltages and

temperatures

The AOZ8014 consists of four identical circuits

comprised of TVS diodes for ESD protection, and a

resistor–capacitor network for EMI/RFI ﬁltering.

A series resistor value of 100Ω and a capacitance

value of 17pF are used to achieve -25dB minimum

attenuation from 800MHz to 3.0GHz. The TVS diodes

provide effective suppression of ESD voltages in excess

of ±17kV (air discharge) and ±17kV (contact discharge).

This exceeds IEC 61000-4-2, level 4 ESD immunity test.

● DFN package, 2.0 x 2.0 mm

● Pb-Free device

Applications

● EMI ﬁltering and ESD protection for data lines

● LCD displays, camera interface, I/O interface

● Portable handheld devices, cell phones,

PDA phones

The AOZ8014 comes in an RoHS compliant, 2.0mm x

2.0mm DFN package and is rated over a -40°C to +85°C

ambient temperature range.
