USB Type-A to Type-C Port Converter with

Protection

MAX20463/MAX20463A

General Description

Benefits and Features

● Designed to USB Type-C R1.3 Specification with

The MAX20463 is a small, integrated USB Type-C

Downstream-Facing Port (DFP) solution used to convert

an existing USB-A head-unit captive-cable port to a head-

unit USB Type-C captive-cable port. When the MAX20463

is designed into an automotive module at the end of the

cable, then the existing upstream head-unit USB-A solu-

tion and the existing USB-A captive-cable housing can be

reused.

Integrated V Discharge

BUS

• USB Type-C 1.5A, 3.0A DFP Controller

• Type-C Current Limit Reduction with V

Dropout

BUS

● Designed for Cooperative Protection with Head-Unit

Protector

• Short-to-Battery and Short-to-Ground Survival on

HVBUS for Upstream Protector to Handle

• Accurate USB Bus Forward Current Threshold

The device protection features include ±15kV/±8kV IEC

61000-4-2 ESD on CC1/CC2, and IEC ESD with short-to-

battery (18V) on SENSE/HVBUS. The MAX20463A sens-

es a short of the passenger cable shield to car battery,

preventing damage to the port. Short-to-ground and short-

to-battery survival are also provided on the HVBUS signal

and defined to operate in concert with the existing head-

unit USB-A charger/protector, allowing coordinated fault

detection and reporting to the head-unit USB host.

• Low R

28mΩ (typ) USB Power Switch

● Robust Design Keeps Vehicle System and Portable

Devices Safe in Automotive Environment

• Optional Shield Short-to-Battery Detection and

External FET Control

• Short-to-BUS Protection on Protected CC1 and

CC2 Outputs

• IEC 61000-4-2 Level-4 ESD Protection (HVBUS,

CC1, CC2, SENSE)

The MAX20463 is available in a small, 3mm x 3mm,

12-pin TDFN package, using very few external compo-

nents.

● 3mm x 3mm 12-Pin TDFN Package

● -40°C to +105°C Operating Temperature Range

● AEC-Q100 Qualified

Applications

● Automotive USB Captive-Cable Housing

● Automotive Downstream USB Modules
