Overview

The PMP40040 reference design is a single channel USB charger for automotive applications. It includes a high switching frequency buck converter which can minimize the size of power components and reduce the system's cost. It includes built-in short-to-battery protection, IEC ESD protection features enhance the system's reliability significantly in automotive application. This design can also handle a 2.1A load current. Its output port supports the USB BC1.2 CDP charging protocol.

Features
  • Linear VBUS droop compensation
  • Short-to-battery protection on protected VBUS, DP_IN and DM_IN pins
  • IEC ESD protection on DP_IN/DM_IN
  • USB BC1.2 CDP charging protocol supported
  • High switching frequency up to 2.1MHz
