GENERAL DESCRIPTION
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), 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. Typical Operating Circuit Benefits andFEATURES
