Key Document


PMP40285 is a dual port USB Type-C™ charger reference design. This design takes an automotive input voltage, the output goes to two USB Type-C port. Each of these ports supplies 5V 3A for USB Type-C™ device. The design is fully compliant with USB type C and backwards compliant with BC1.2 and DCP configurations. The design is cost-effective due to one chip solution for dual USB Type-C DFP outputs and the low component count.

  • Dual channel USB Type-C™ DFP design
  • 90% efficiency at 12V input and full load with USB switches
  • Integrated IEC ESD protection
  • USB BC1.2 DCP charging protocols supported
  • Low component count
