The MAX16919 provides 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 device supports both Hi-Speed USB (480Mbps) and full-speed USB (12Mbps) operation. In addition, the device includes integrated circuitry to enable fast-charging for consumer devices adhering to the Hi-Speed USB host-charger port-detection protocol.
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 device is capable of a short-to-battery condition of up to +18V. Short-to-GND and overcurrent protection are also provided on the HVBUS output to protect the internal BUS power rail from overcurrent faults.
The device features high-ESD protection to ±15kV Air Gap method and ±8kV Contact method on all protected HVBUS, HVD+, and HVD- outputs.
The device features two low 4.0Ω on-resistance Hi-Speed USB switches and a current-limited low-voltage 22mΩ BUS switch, and provides an integrated high-voltage external power-switch controller. The BUS switch can start up into large capacitive noncompliant USB loads. The device also features an enable input, a fault output, and an integrated host-charger port-detection circuit adhering to the USB 2.0 battery charging specification.
The device is available in a 16-pin QSOP package, and operates over -40°C to +105°C temperature range.
