EZ-PD™ Barrel Connector Replacement (BCR) USB-C™ Controller

Cypress' EZ-PD BCR enables users to quickly convert their devices from being powered through a barrel connector to being powered via USB-C

Image of Cypress' EZ-PD™ Barrel Connector Replacement (BCR) USB-C Controller Cypress' EZ-PD BCR is a highly-integrated USB Type-C port controller targeting electronic devices that have legacy barrel connectors (up to 100 W) or USB micro-B connectors for power such as drones, smart speakers, power tools, and other rechargeable devices. EZ-PD BCR complies with the latest USB Type-C and USB Power Delivery (PD) standards. It enables users to quickly convert their devices from being powered through a barrel connector to being powered via the USB-C connector with few external components and without requiring firmware development.

EZ-PD BCR integrates a complete USB Type-C transceiver, USB PD policy manager, a load switch controller with a soft start, all termination resistors required for a USB Type-C port, and system-level ESD protection.

Features

  • Supports USB Type-C and Power Delivery 3.0 programmable power supply
  • Supports Apple charging (2.4 A)
  • UFP-only with configurable RD and RD-DB
  • Integrated analog blocks
    • 30 V-tolerant regulator
    • VBUS-to-CC short protection
    • On-chip overvoltage protection (OVP)
    • Packages: 24-pin QFN
    • Supports extended industrial temperature range (-40°C to +105°C)

EZ-PD BCR Evaluation Kit (CY4533)

Replace a barrel power connector with USB-C in three simple steps using the CY4533 EZ-PD BCR Kit:

  1. Select a commercially available USB-C power adapter that supports the desired USB PD power profile.
  2. Set up the desired USB PD power profile with Cypress' EZ-PD BCR Kit and quickly prototype by converting the USB-C power input to a barrel connector output to the product (e.g., a smart speaker). No firmware development is required.
  3. Embed Cypress' CYPD3177 BCR controller into the product and replace the barrel receptacle with a USB-C receptacle. The product can now be powered by any USB-C power adapter supporting the required power profile.
