MAX20043F

Automotive Hi-Speed USB 2.0 Protectors

Industry-Leading Overvoltage and ESD Protection for Automotive USB


Please check latest availability status for a specific part variant.

Description

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.
