The TPD6E004 ensures that the core circuitry is protected and the system is functioning properly in the event of an ESD strike. For proper operation, the following layout/design guidelines should be followed: 1. Place the TPD6E004 solution close to the connector. This allows the TPD6E004 to take away the energy associated with ESD strike before it reaches the internal circuitry of the system board. 2. Place a 0.1-F capacitor very close to the VCC pin. This limits any momentary voltage surge at the IO pin during the ESD strike event. 3. Make sure that there is enough metallization for the VCC and GND loop. During normal operation, the TPD6E004 consumes nA leakage current. But during the ESD event, VCC and GND may see 15 A to 30 A of current, depending on the ESD level. Sufficient current path enables safe discharge of all the energy associated with the ESD strike. 4. Leave the unused IO pins floating. 5. The VCC pin can be connected in two different ways: a. If the VCC pin is connected to the system power supply (a 0.1-F capacitor at VCC is recommended for ESD bypass), the TPD6E004 works as a transient voltage suppressor for any signal swing above VCC + Vd. b. If the VCC pin is not connected to system power supply (a 0.1-F capacitor is still recommended at the VCC pin for ESD bypass), the TPD6E004 can tolerate higher signal swing in the range up to VBR. Note that initially the bypass capacitor is charged by the signals through clamp diode. 6 Submit Documentation Feedback Copyright (c) 2008, Texas Instruments Incorporated Product Folder Link(s): TPD6E004 PACKAGE OPTION ADDENDUM www.ti.com 14-Aug-2010 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Drawing Pins Package Qty Eco Plan (2) Lead/ Ball Finish MSL Peak Temp (3) Samples (Requires Login) TPD6E004RSER ACTIVE UQFN RSE 8 3000 TBD Call TI Call TI Request Free Samples TPD6E004RSERG4 ACTIVE UQFN RSE 8 3000 TBD Call TI Call TI Request Free Samples (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
