7 Detailed Description

7.1 Overview

The TPD3E001 is a three-channel Transient Voltage Suppressor (TVS) based Electrostatic Discharge (ESD) protection diode array. The TPD3E001 is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4). This device has a 1.5-pF IO capacitance per channel, making it ideal for use in high-speed data IO interfaces. The ultra low leakage current (< 1 nA maximum) is suitable for precision analog measurements in applications like glucose meters and heart rate monitors. The wide voltage range on VCC (up to 5.5V) gives this device the flexibility to be used in a wide variety applications. Having 3-channels of ESD protection makes this device particularly well suited to protect a micro-AB USB connector, which has three signal lines to be protected (D+, D-, ID). The VBUS pin can also be protected by connecting it to VCC on TPD3E001. Therefore, TPD3E001 is a one-chip solution to provide Level 4 IEC 61000-4-2 ESD protection on every pin of the micro-AB USB connector.

7.3 Feature Description

TPD3E001 is a uni-directional ESD protection device with low capacitance. The device is constructed with a central ESD clamp that features two hiding diodes per line to reduce the capacitive loading. This central ESD clamp is also connected to VCC to provide protection for the VCC line. Each IO line is rated to dissipate ESD strikes at the maximum level specified in the IEC 61000-4-2 level 4 international standard. The TPD3E001's low loading capacitance makes it ideal for protection high-speed signal terminals.

7.4 Device Functional Modes

TPD3E001 is a passive-integrated circuit that activates whenever voltages above VBR or below the lower diodes Vforward (–0.6V) are present upon the circuit being protected. During ESD events, voltages as high as ±15 kV can be directed to ground and VCC via the internal diode network. Once the voltages on the protected lines fall below the trigger voltage of the TPD3E001 (usually within 10's of nano-seconds) the device reverts back to a high-impedance state.
