The MAX20046 device 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. The device supports USB Hi-Speed (480Mbps), USB full-speed (12Mbps), and USB low-speed (1.5Mbps) operation. The short-circuit protection features include short-to-battery on the protected HVBUS, as well as short-to-HVBUS and short-to-battery on the protected HVD+ and HVD-. Short-to-GND and overcurrent protection are also provided on the protected HVBUS output to protect the internal BUS power rail from overcurrent faults. The device features high-ESD protection to ±15kV Air Gap and ±8kV Contact on the protected HVBUS, HVD+, and HVD- outputs. The device features a 500mΩ (max) USB power switch, and two low on-resistance (RON), USB 2.0 data switches. This device also features an enable input, fault output, 10ms fault-recovery time, 1ms overcurrent-blanking time, and integrated overcurrent autoretry.
