Product Details


USB PD and Type-C Features

  • Complies with USB PD and USB Type-C specifications
  • Supports implementation of various system PD roles: P, P/C, C, C/P
  • Supports Type-C role configurability
  • Type-C role (DFP, UFP, DRP) is Non-Volatile Memory (NVM) and register programmable based on OEM platform requirements
  • Implements UFP role pull-down behavior to handle dead battery condition on battery-powered platforms
  • Supports register programmable and variable ‘Rp’ indication (for DRP/DFP usage and accessory detection)
  • Implements 'Rd' indication on CC pin (for device side implementation)
  • CC detection/indication scheme based on Type-C role
  • Indication of orientation detection via CC_ORIENT pin and status register(s)
  • Debug and audio accessory detection and indication in status register(s)
  • Cooperatively works under the control of policy controller MCU for power delivery negotiation and contract(s), alternate mode and VDM exchanges
  • Implements BMC (de) coding, 4B5B symbol (de) coding, CRC generation/checking, PD packet assembling/disassembling including preamble, SOP, EOP, Good CRC response, retries, hard and cable resets
  • PD PHY and protocol layer interface control and status update handled via SPI/I2C interface

SOP Configurability

  • Register programmable to generate and receive SOP, SOP', SOP'-debug, SOP", SOP"-debug'' in DFP/DRP (host use case)
  • Register programmable to receive and respond on SOP, SOP'-debug and SOP"-debug commands
  • Supports low RON VCONN switch with enable/disable (Hi-Z) support
  • Capable of maximum current delivery of 1 A over 2.7 V to -5.5 V
  • Supports register programmable forward current protection control
  • Supports register programmable reverse current protection
