MAX16970/MAX16971
3A Automotive Hi-Speed USB Protectors with
Apple iPhone/iPad and USB 2.0 Charge Detection
Benefits and Features
General Description
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).
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.
Each device features high-ESD protection to ±15kV Air
Gap method and ±8kV Contact method on all protected
HVBUS, HVD+, and HVD- outputs.
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

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.
The devices are available in 16-pin QSOP and
16-pin (4mm x 4mm) TQFN packages and oper-
ate over the -40°C to +105°C temperature range. The
MAX16970GEEA/ V+ and MAX16971GEEA/V+ are drop-in
compatible with MAX16969DGEE/V+ and MAX16969BGEE/
V+, respectively.
