Description

PMP40269 is a dual port car charger reference design. It has a USB Type-C™ port and a USB type-A port. The USB Type-C port can provide 5V 1.5A to USB Type-C device. The type-A port can provide 5V 2.4A, it is also capable of compensating for the effects on voltage droop when a smartphone or tablet is connected to the port using a long cable. It has a good system reliability with the integrated IEC ESD and short-to-VBUS protections. The solution efficiency is greater than 91% with USB switches at 12V input.

Features
  • Fully integratedreference design for USB Type-C DFP port
  • Short-to-VBUS protection on DP_IN and DM_IN
  • IEC ESD protection on CC1/CC2 and DP_IN/DM_IN
  • USB BC1.2 DCP charging protocols supported
  • High efficiency up to 91.7% with full load
