Description

The MAX16942E/MAX16943E/MAX16944E 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 MAX16942E/MAX16943E/MAX16944E support both USB Hi-Speed (480Mbps) and USB full-speed (12Mbps) operation.

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 MAX16942E/MAX16943E/MAX16944E 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 MAX16942E/MAX16943E/MAX16944E feature high ESD protection to ±15kV Air Gap and ±8kV Contact on all protected HVBUS, HVD+, and HVD- outputs.

The MAX16942E/MAX16943E/MAX16944E feature a low on-resistance (RON), 0.14Ω(max) USB power switch, and two low on-resistance (RON) of 4Ω (typ) USB 2.0 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 MAX16942E/MAX16943E/MAX16944E are available in a lead-free, 16-pin QSOP package and operate over the -40°C to +105°C temperature range.
