MAX16972AGTEB/V+

MAX16972AGTEB/V+ is a 3A automotive high-speed USB protector. It provides high-ESD and short-circuit protection for the low-voltage internal USB data and USB power line in automotive radio, navigation, connectivity, and USB hub applications. This device supports both High-speed USB (480Mbps) and full-speed USB (12Mbps) operation. In addition, this device includes 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). The short-circuit protection features include short-to-battery on the protected HVBUS, HVD+, and HVD- outputs, as well as short-to-HVBUS on the protected HVD+ and HVD outputs. This device is capable of a short-to-battery condition of up to +18V. It is used in applications such as automotive radio and navigation, USB hub, automotive connectivity, telematics.
