USB Type-C power delivery PHY and protocol IC

Complying with USB PD and Type-C specifications and delta updates of PD spec, PTN5100 is a single port USB Type-C Power Delivery (PD) PHY and Protocol IC that provides Type-C Configuration channel interface and USB PD Physical and Protocol layer functions to a System PD Port Policy Controller (Policy Engine and Device Policy Manager, Alternate mode controller). This IC is targeted for a wide range of platforms and PC Accessories applications.

Implementing VCONN low RON switch with register programmable Forward Current protection feature, PTN5100 can support system realization of the following PD roles: (i) Provider (P) only, (ii) Provider/Consumer (P/C) (iii) Consumer only (C) (iv) Consumer/Provider (C/P). It can be programmed to operate in Type-C specific Upstream Facing Port (UFP), Downstream Facing Port (DFP) or Dual Role Port (DRP) role.
