Ethernet ESD Protection
For the hundreds of electronic circuits in a vehicle, the automotive Ethernet is becoming a popular choice due to its ability to enable faster communication, flexibility and cost-effectiveness. To protect automotive's growing Ethernet bus speeds, ultra-low capacitance with low voltage clamping capability is necessary. Semtech's industry-leading TVS protection devices safeguard high-speed automotive Ethernet from electrostatic discharge (ESD) and other overvoltage transients.
High Speed – SERDES Protection
Drivers and vehicles now rely more heavily on Advanced Driver Assistance Systems (ADAS) for which high speed SERDES interfaces like GMSL, FPD-Link, APIX, MIPI A-Phy, ASA are used for communication. Semtech’s industry leading transient voltage suppressor (TVS) protection devices safeguard automotive high-speed interfaces from electrostatic discharge (ESD) and other overvoltage transients are fully compliant with AEC-Q100 specification and are designed with ultra-low line capacitance which is a requirement for high-speed interfaces.
CAN Bus Protection
There are several in-vehicle network (IVN) protocols for data transmission between ECUs inside a vehicle. The most popular communication mechanism in modern vehicles is the Controller Area Network (CAN) bus. When designing a CAN interface system in a harsh automotive environment with 50 to 100 ECUs, ensuring sufficient protection from Electrical Overstress Events (EOS) is imperative. Semtech's well-performing and reliable portfolio of TVS products protects high-speed automotive CAN buses as well as other communication buses.
Antenna Protection
Antenna and RF interfaces are common in a wide host of electronics equipment. These antenna interfaces can be highly susceptible to ESD and overvoltage transient threats. Semtech offers low-capacitance TVS devices that will both safely arrest dangerous transient spikes while also presenting minimal capacitance to not compromise the RF signal integrity.
Infotainment Protection
Most infotainment systems in today´s automotive world are composed of a head unit and media interface system. The media interface can receive inputs from USB, HDMI, SD Cards, or Audio Jacks. These interfaces cause the internal system circuitry to be at risk of electrostatic discharge (ESD) strikes. Semtech provides industry leading, low-clamping voltage ESD protection solutions to safeguard these interfaces from ESD and overvoltage transient threats.
