EVALUATION KIT AVAILABLE MAX20042FMAX20044F Automotive Hi-Speed USB 2.0 Protectors General Description Benefits and Features Accurate Bus Current Limiting with The MAX20042F, MAX20043F, and MAX20044F devices Minimal Voltage Drop provide high ESD and short-circuit protection for the Low R 90m (max) USB Power Switch ON low-voltage internal USB data and USB power line in auto- 0.65A (typ), MAX20042F motive radio, navigation, connectivity, and USB hub appli- 1.0A (typ), MAX20043F cations. The devices support USB Hi-Speed (480Mbps), 1.3A (typ), MAX20044F USB full-speed (12Mbps), and USB low-speed (1.5Mbps) Targeted Features for Optimized USB Performance operation, as well as USB on-the-go (OTG) functionality. Two R 4 (typ) USB 2.0 Data Switches ON The short-circuit protection features include short-to- 480Mbps or 12Mbps USB 2.0 Operation battery on the protected HVBUS, HVD+, and HVD- 10ms Fault-Recovery Time outputs, as well as short-to-HVBUS on the protected 1ms Overcurrent Blanking Time HVD+ and HVD- outputs. The devices are capable of a 5.67V (typ) Fixed HVBUS Protection Trip Threshold short-to-battery condition of up to +18V. Short-to-GND Robust for the Automotive Environment protection and overcurrent protection are also provided Short-to-Battery and Short-to-GND Protection on on the protected HVBUS output to protect the internal Protected HVBUS Output BUS power rail from an overcurrent fault. Short-to-Battery and Short-to-BUS Protection on Protected HVD+ and HVD- Outputs The devices feature high ESD protection to 15kV Air Gap Tested to ISO 10605 and IEC 61000-4-2 ESD and 8kV Contact on the protected HVBUS, HVD+, and Standards HVD- outputs. 16-Pin (3.90mm x 4.94mm) QSOP Package The devices feature a low on-resistance (R ), ON -40C to +105C Operating Temperature Range 90m (max) USB power switch, and two low on- AEC-Q100 Qualified resistance (R ), 4 (typ) USB 2.0 data switches. These ON devices also feature an enable input, a fault output, a Applications 10ms fault-recovery time, a 1ms overcurrent blanking Automotive USB Protection time, and an integrated overcurrent autoretry.
