MAX20042F - Analog Devices

MAX20042F Automotive Hi-Speed USB 2.0 Protectors

The MAX20042F, MAX20043F, and MAX20044F devices provide 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. The devices support USB Hi-Speed (480Mbps), USB full-speed (12Mbps), and USB low-speed (1.5Mbps) operation, as well as USB on-the-go (OT.

Features

include short-tobattery on the protected HVBUS, HVD+, and HVDoutputs, as well as short-to-HVBUS on the protected HVD+ and HVD- outputs. The devices are capable of a short-to-battery condition of up to +18V. Short-to-GND protection and overcurrent protection are also provided on the protected HVBUS output to protect the internal BUS power rail from an overcurrent fault. The devices feature high ESD protection to ±15kV Air Gap and ±8kV Contact on the protected HVBUS, HVD+, and HVD- outputs. The devices feature a low on-resistance (RON), 90mΩ (max) USB power switch, and two low onresistance (RON).
