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
ON
• 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
