Maxim Built-in 3A Automotive Hello-Pace USB Protectors


Maxim Integrated 3A Automotive Hi-Speed USB Protectors provide high-ESD and short-circuit protection for low-voltage internal USB data and USB power line. The protectors are ideal for use in automotive radio, navigation, connectivity, and USB hub applications. The devices support Hi-Speed USB (480Mbps) and full-speed USB (12Mbps) operation. The devices also include integrated circuitry to enable fast charging for consumer devices that adhere to either the Apple® method or the Hi-Speed USB host-charger port-detection protocol and support USB on-the-go (OTG).
