USB Type-A to Type-C Port Converter with Protection

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 solution and the existing USB-A captive-cable housing can be reused.

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 senses 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.

The MAX20463 is available in a small, 3mm x 3mm, 12-pin TDFN package, using very few external components.
