Optimized on-chip ESD protection to enable high-speed Ethernet in cars.

In the past most Electronic Control Units (ECU) used CAN and LIN interfaces to connect to sensors, actuators and each other. However, the newest applications need (much) faster communication options. Gigabit automotive ethernet is pushed by many in the industry as the perfect solution.

With its local ESD clamp approach, Sofics provides the best solution to protect those high-speed chip interfaces against Electrostatic Discharge events.

Selecting custom ESD IP for your next IC

Fabless semiconductor companies usually use third-party IP blocks when developing ICs. An important IP is on-chip ESD protection. Caution must be exercised in choosing the right ESD IP to avoid patent infringement and inefficient ESD clamps.

Thomas Ako made a presentation about the IP selection process on the 2021 IP-SOC event in Grenoble in December 2021.

Introduction: ESD protection concepts for I/Os

There are many different approaches to ensure effective ESD protection for integrated circuits. It is important to select the right approach for each interface and power domain. This article outlines the main options for Interface protection.
