ABRIDGED DATA SHEET EVALUATION KIT AVAILABLE MAX16970/MAX16971 3A Automotive Hi-Speed USB Protectors with Apple iPhone/iPad and USB 2.0 Charge Detection General Description Benefits and Features The MAX16970/MAX16971 provide high-ESD and short- Minimized Voltage Drop on Bus Line Due to Industry- Leading RDS Helps Meet USB circuit protection for the low-voltage internal USB data (ON) Voltage Specifications at Device Connector and USB power line in automotive radio, navigation, Current-Limited 31m (typ) BUS Switch with High- connectivity, and USB hub applications. The devices sup- Capacitive Load Capability port both Hi-Speed USB (480Mbps) and full-speed USB (12Mbps) operation. In addition, the devices also include Robust Overvoltage and ESD Protection for integrated circuitry to enable fast-charging for consumer Automotive Environment Saves on External devices adhering to either the Apple method or the Protection Components Hi-Speed USB host-charger port-detection protocol and Short-to-Battery and Short-to-GND Protection on support USB On-The-Go (OTG). Protected HVBUS Output Short-to-Battery and Short-to-HVBUS Protection The short-circuit protection features include short-to-bat- on Protected HVD+ and HVD- Outputs tery on the protected HVBUS, HVD+, and HVD- outputs, Two 4.0 (typ) R USB 2.0 Data Switches as well as short-to-HVBUS on the protected HVD+ and ON Integrated Overcurrent and Short-Circuit Autoretry HVD- outputs. The devices are capable of a short-to-bat- High ESD Protection (HVD+, HVD-, HVBUS) tery condition of up to +18V. Short-to-GND and overcur- 15kV Human Body Model rent protection are also provided on the HVBUS output to 15kV IEC 61000-4-2 Air Gap protect the internal BUS power rail from overcurrent faults. 8kV IEC 61000-4-2 Contact Each device features high-ESD protection to 15kV Air 20ms Fault-Blanking Timeout Period Gap method and 8kV Contact method on all protected Automatic Transitioning of Charge Modes Through HVBUS, HVD+, and HVD- outputs. Intelligent State Machine for Seamless Device Each device features two low 4.0 on-resistance Hi-Speed Integration USB switches, a current-limited low-voltage 31m BUS Integrated Apple iPhone 1.0A Dedicated Charging switch, and provides an integrated high-voltage external Mode power-switch controller. The BUS switch can start up into Integrated Apple iPad 2.1A Dedicated Charging large capacitive noncompliant USB loads. The devices Mode also feature an enable input, a fault output, integrated USB-IF BC1.2 Charging Downstream Port (CDP) Apple iPhone /iPad fast-charging termination resis- and Dedicated Charging Port (DCP) Modes tors, and an integrated host-charger port-detection circuit Chinese Telecommunication Industry-Standard adhering to the USB 2.0 battery charging specification YD/T 1591-209 version 1.2.
