FUSB302B Programmable USB Type‐C Controller w/PD
FUSB302B
Description The FUSB302B targets system designers looking to implement
a DRP/SRC/SNK USB Type-C connector with low amount of programmability.
The FUSB302B enables the USB Type-C detection including attach, and orientation. The FUSB302B integrates the physical layer of the USB BMC power delivery protocol to allow up to 100 W of power and role swap. The BMC PD block enables full support for alternative interfaces of the Type-C specification.
Features
• Dual-role Functionality with Autonomous DRP Toggle • Ability to Connect as Either a Host or a Device Based on What Has
Been Attached
• Software Configurable Either as a Dedicated Host, Dedicated
Device, or Dual Role ♦ Dedicated Devices can Operate both on a Type-C Receptacle or
a Type-C Plug with a Fixed CC and VCONN Channel
• Full Type-C 1.2 Support. Integrates the Following Functionality of
the CC Pin: ♦ Attach/Detach Detection as Host ♦ Current Capability Indication as Host ♦ Current Capability Detection as Device ♦ Audio Adapter Accessory Mode ♦ Debug Accessory Mode ♦ Active Cable Detection
• Integrates CCx to VCONN Switch with Over-current Limiting for
Powering USB3.1 Full Featured Cables
• USB Power Delivery (PD) 2.0, Version 1.2 Support:
♦ Automatic GoodCRC Packet Response ♦ Automatic Retries of Sending a Packet if a GoodCRC is Not
Received ♦ Automatic Soft Reset Packet Sent with Retries if Needed ♦ Automatic Hard Reset Ordered Set Sent
• Dead Battery Support (SNK Mode Support when No Power Applied) • Low Power Operation: ICC = 25 mA (Typical) • AEC−Q100 Automotive Qualified Temperature Grade 2:
(−40°C to +105°C)
• Packaged in:
♦ 9-ball WLCSP (1.215 mm × 1.260 mm) ♦ 14-lead MLP (2.5 mm × 2.5 mm, 0.5 mm Pitch)
