Cypress’ EZ-PD BCR controller offers a high level of integration in a small footprint package that minimizes bill-of-material cost and simplifies designs, enabling developers to quickly convert their products to be powered via a USB-C connector with few external components and no firmware required. Cypress accelerates the transition to USB-C connectors with the new EZ-PD BCR Kit, which enables product developers to quickly prototype without requiring firmware development. More information on the solution is available at www.cypress.com/bcr.
“Using USB-C with Power Delivery as the universal power adapter solution
makes sense across the board,” said
The EZ-PD BCR Kit enables product developers to quickly prototype the conversion of their products from a conventional power adapter to USB PD in three steps:
- One, select a commercially available USB PD power adapter that supports the desired power profile;
- Two, set up the desired USB PD power profile with the EZ-PD BCR Kit and quickly prototype with no firmware development required;
- And three, embed the EZ-PD BCR controller into the product, replacing the barrel receptacle with a USB-C receptacle.
The product can then be powered by any USB-C power adapter supporting the desired USB Power Delivery profile, giving the manufacturer the option to allow consumers to use their own USB-C power adapters instead of providing one in-box.
Cypress will demonstrate the EZ-PD BCR solution at Embedded World 2019
Cypress’ EZ-PD BCR solution complies with the latest USB Type-C and USB PD 3.0 standards. The BCR controller integrates a complete Type-C USB-PD transceiver, a load switch controller with a soft start, all termination resistors required for a USB-C port and system-level ESD protection. The one-chip solution minimizes bill-of-material costs for USB-C power adapters by integrating error amplifiers for constant voltage, constant current and PPS applications, a 30 V regulator that allows direct operation from VBUS, VBUS short protection on configuration channel (CC) pins, gate drivers for high-voltage power FETs, a low side current sense amplifier, and dedicated hardware for legacy charger detection protocols plus system level electrostatic discharge (ESD) protection. Overvoltage and overcurrent circuitry protects systems against power overloads and other faulty operating conditions.
The CYPD3177 EZ-PD BCR controller is now in production in a 24-pin QFN
(16 mm2) package. Designers can get started with the EZ-PD
BCR Kit (CY4533), which is now available for
About Cypress’ EZ-PD Portfolio
Cypress’ EZ-PD portfolio of USB-C controllers also includes CCG1, the world’s first programmable USB-C controller, CCG2, the market’s smallest programmable USB-C solution, CCG3, the market’s most integrated programmable USB-C solution, CCG4, the world’s first two-port USB-C solution, and CCG5 and CCG6, the market’s first two-port USB-C solutions optimized for Thunderbolt notebook and desktop PCs. The EZ-PD portfolio was the first to support the latest USB PD 3.0 specification, which enables more robust end-to-end power delivery and charging solutions for laptop and mobile devices. The portfolio also includes versions of CCG2 and CCG3PA that are AEC-Q100 certified for automotive-grade performance, enabling fast charging of portable electronics in vehicles.
The USB-C standard is gaining rapid support with top-tier electronics manufacturers by enabling slim industrial designs, easy-to-use connectors and cables, and the ability to transmit multiple protocols and deliver up to 100 Watts of power. The USB-C standard’s 2.4-mm-high connector plug is significantly smaller than the current 4.5-mm USB Standard-A connector.
