TPD12S015 PCB Layout Guidelines

From Texas Instruments Standard Linear and Logic

The TPD12S015 is a multifunction ESD protection device targeting portable HDMI (High Definition Multimedia Interface) applications. This application note focuses on layout guidelines for using the TPD12S015 DSBGA (Die Sized Ball Grid Array) 28 ball package mapped to HDMI C-type and D-type connectors. This solution is geared toward the smallest possible board area. To meet that goal, the TPD12S015 provides integrated level shifter capabilities from 1.1V - 3.6V (VCCA range) to 5V. Additionally, the device is capable of generating 5V from a 2.3V-5V battery using internal boost converter circuitry.

Circuit Protection Devices
Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component.
Electrostatic Discharge (ESD) Suppressors
ESD suppressors are semiconductors that protect electronic components and systems from electrostatic discharge (ESD).
Transient Voltage Suppressor Diodes (TVS)
Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time.
