Semtech 推出适用于汽车 CAN 总线节点并符合 AEC-Q100 标准的新型防护阵列

汽车 ESD 防护平台的扩展为 CAN 总线提供卓越的保护

CAMARILLO, Calif., Feb. 5, 2019 — Semtech Corporation（纳斯达克股票代码：SMTC）是行业领先的供应商，提供高性能模拟和混合信号半导体产品以及先进算法。公司今天推出了一种适用于汽车 CAN 总线节点并符合 AEC-Q100 标准的新型防护阵列。新型低电容 24V (Vrwm) 瞬态电压防护 µClamp® 阵列经过优化，可保护汽车 CAN 总线节点免受静电放电 (ESD) 和过电压瞬变威胁。

“CAN continues to be an important and prolific bus used in today’s automotive system designs,” said Tamir Reshef, Product Marketing Director for Semtech’s Protection Products Group. “The new µClamp2492SQ, with its superior ESD robustness and low clamping voltage performance, provides automotive engineers a much needed solution to safeguard CAN nodes.”

The CAN networking bus has long served as the backbone of vehicle networking and is widely used in today’s vehicles. To adequately provide ESD immunity, CAN nodes require ESD protection devices with 24V working voltage and a low ESD clamping voltage to safeguard bus nodes from the harsh electrical environment in the car. The two-line, 24V µClamp2492SQ offers a low ESD clamping voltage while minimizing loading capacitance, making it suitable for higher speed versions of CAN, including CAN 2.0 and CAN FD.

The µClamp2492SQ is housed in an industry standard SOT-23 3L package, and provides two lines of robust transient protection. The device far exceeds the IEC61000-4-2 ESD immunity standards, offering an industry-leading protection level of ±30kV air and ±30kV contact, and is qualified to Grade 1 of the AEC-Q100 Automotive Standard.

Key Features of µClamp2492SQ

• Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact); IEC 61000-4-4 (EFT) 4kV (5/50ns); IEC 61000-4-5 (Lightning) 5A (8/20μs)
• 24V working voltage protection
• Protects two I/O lines
• Low capacitance (<18pF line-to-line)
• Industry standard SOT-23 package
• AEC-Q100 qualified to Grade 1
• Pb-Free and RoHS/WEEE compliant
