3A Automotive Hi-Speed USB Protectors with

Apple iPhone/iPad and USB 2.0 Charge Detection

General Description

Beneﬁts and Features

● Minimized Voltage Drop on Bus Line Due to Industry-

The MAX16970/MAX16971 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 sup-

port both Hi-Speed USB (480Mbps) and full-speed USB

(12Mbps) operation. In addition, the devices also include

integrated circuitry to enable fast-charging for consumer

devices adhering to either the Apple method or the

Hi-Speed USB host-charger port-detection protocol and

support USB On-The-Go (OTG).

Voltage Specifications at Device Connector

• Current-Limited 31mΩ (typ) BUS Switch with High-

Capacitive Load Capability

● Robust Overvoltage and ESD Protection for

Automotive Environment Saves on External

Protection Components

• Short-to-Battery and Short-to-GND Protection on

Protected HVBUS Output

• Short-to-Battery and Short-to-HVBUS Protection

on Protected HVD+ and HVD- Outputs

The short-circuit protection features include short-to-bat-

tery 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-bat-

tery condition of up to +18V. Short-to-GND and overcur-

rent protection are also provided on the HVBUS output to

protect the internal BUS power rail from overcurrent faults.

• Two 4.0Ω (typ) R

USB 2.0 Data Switches

• Integrated Overcurrent and Short-Circuit Autoretry

• High ESD Protection (HVD+, HVD-, HVBUS)

• ±15kV Human Body Model

• ±15kV IEC 61000-4-2 Air Gap

• ±8kV IEC 61000-4-2 Contact

• 20ms Fault-Blanking Timeout Period

Each device features high-ESD protection to ±15kV Air

Gap method and ±8kV Contact method on all protected

HVBUS, HVD+, and HVD- outputs.

● Automatic Transitioning of Charge Modes Through

Intelligent State Machine for Seamless Device

Integration

Each device features two low 4.0Ω on-resistance Hi-Speed

USB switches, a current-limited low-voltage 31mΩ 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 devices

also feature an enable input, a fault output, integrated

• Integrated Apple iPhone 1.0A Dedicated Charging

• USB-IF BC1.2 Charging Downstream Port (CDP)

and Dedicated Charging Port (DCP) Modes

• Chinese Telecommunication Industry-Standard

YD/T 1591-209

Apple iPhone /iPad fast-charging termination resis-

tors, and an integrated host-charger port-detection circuit

adhering to the USB 2.0 battery charging specification

version 1.2.

• USB On-The-Go (OTG) Support

The devices are available in 16-pin QSOP and
