MAX20044F Series

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 (OTG) functionality.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. 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 on-resistance (RON), 4Ω (typ) USB 2.0 data switches. These devices also feature an enable input, a fault output, a 10ms fault-recovery time, a 1ms overcurrent blanking time, and an integrated overcurrent autoretry.The MAX20042F, MAX20043F, and MAX20044F are available in a lead-free, 16-pin QSOP package and operate over the -40°C to +105°C temperature range.ApplicationsAutomotive USB Protection
