Analog Devices Inc. MAX20463 Automotive USB Type-A to Type-C Converter

Analog Devices MAX20463 Automotive USB Type-A to Type-C Converters are used to convert an existing USB-A head-unit captive-cable port to a head-unit USB Type-C™ captive-cable port. The MAX20463 devices are designed for automotive modules. At the end of the cable, an existing upstream head-unit USB-A solution and 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 a 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. This allows coordinated fault detection and reporting to the head-unit USB host. The device is compliant with the USB Type-C specification.

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