MAX16972/MAX16972A

3A Automotive Hi-Speed USB

Protectors with Apple iPhone/iPad

and USB 2.0 Charge Detection

General Description

Beneﬁts and Features

● 900MHz Bandwidth USB 2.0 Data Switches

The MAX16972/MAX16972A provide high-ESD and

short-circuit protection for the low-voltage internal USB

data and USB power line in automotive radio, naviga-

tion, connectivity, and USB hub applications. The devices

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

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

integrated circuitry to enable fast charging for consumer

devices that adhere to either the Apple method or the

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

support USB on-the-go (OTG).

● Industry-Leading R

Minimizes Voltage Drop

DS(ON)

on Bus Line to Help Meet USB 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

Theshort-circuitprotectionfeaturesincludeshort-to-battery

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-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.

• 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

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

Gap method and ±8kV Contact method on all protected

HVBUS, HVD+, and HVD- outputs.

• 20ms Fault-Blanking Timeout Period

● 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

high-capacitance noncompliant USB loads. The devices

also feature an enable input, a fault output, integrated

Apple iPhone /iPad fast-charging termination resistors,

and an integrated host-charger port-detection circuit that

adheres to the USB 2.0 battery-charging specification

version 1.2.

• Integrated Apple iPhone 1.0A Dedicated Charging

Mode

• Integrated Apple iPad 2.1A Dedicated Charging

Mode

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

and Dedicated Charging Port (DCP) Modes

• Chinese Telecommunication Industry-Standard

YD/T 1591-209

The devices are available in 16-pin QSOP and 16-pin

(4mm x 4mm) TQFN packages, and operate over the

-40°C to +105°C temperature range. The MAX16972 and

MAX16972A are drop-in compatible with the MAX16970,

MAX16971, MAX16970A, MAX16971A, MAX16917,

MAX16919, and MAX16969 devices.

• USB On-The-Go (OTG) Support

● AEC-Q100 Qualified

Typical Operating Circuit and Ordering Information appear

at end of data sheet.

Applications

● Automotive Radio and Navigation

● USB Hub

● Automotive Connectivity

● Telematics
