What is Power Delivery
Power supply up to 100W (20V/5A) exceeding USB2.0/3.0 is possible. Furthermore, it is possible to perform data communication in Alternate Mode and data roll (swap USB host and device). By utilizing Power Delivery, you can contribute to increasing the number of compatible devices and shortening charging time.
(Reference) Conventional: USB2.0 = 5V/500mA (2.5W), USB3.0 = 5V/900mA (4.5W)

Type-C market trends
With Type-C, data/power/image transfer can be achieved with a single cable, and in recent years it has been increasingly adopted mainly for PCs/smartphones. In the future predicted by the world, it is said that Type-C will be standardized in cars in 5 years, and that all existing power ports will be replaced with Type-C chargers/outlets in 10 years.
The adoption of Type-C in smart speakers, conference system equipment, wearable cameras, and game consoles is also on the rise, and the wave of market launches is surging.
Type-C realizes universalization of AC adapter
Existing AC adapters have unique connector shapes and are not interchangeable, so the number of AC adapters increases in proportion to the number of products purchased by users, which increases the hassle of management and disposal.
As a solution to these issues, a true universal adapter can be realized by using a Type-C connector.
Infineon's EZ-PDTM BCR products enable easy replacement of existing adapters
■ Overview of EZ-PDTM BCR (CYPD3177)
・Easily compatible with Type-CPD protocol with IC alone
・Reduce development period without FW development
・USBIF certified
Type-C PD Design Issues Engineers Face
Converting a barrel connector to Type-C requires deep knowledge. Firmware development is required to implement the USB PD stack. Infineon's BCR products support the USB PD profile of USB-IF certified and popular Type-C adapters. Since it is possible to set the PDO only with voltage dividing resistors, there is no need to develop firmware, shortening the development period, and furthermore, it is possible to consider BOM cost reduction due to the enhancement of protection functions.
■ Protection function
・Short circuit protection for adjacent VBUS-CC terminals
・On-chip overvoltage protection function (OVP)
・ESD protection function (CC, VBUS_IN, DC_OUT, D+, D-, HPI_SDA and HPI_SCL )
・IEC61000-4-2 level 4C compliant, ±8-kV contact discharge and ±15-kV air discharge
■ Other main functions
・USB PD 3.0 compatible (excluding Programmable Power Supply (PPS))
・Supports sync mode only Upstream Facing Port (UFP)
・Supports various PDOs 5V, 9V, 12V, 15V, 19V, 20V, up to 5A
・Supports I2C host communication
・PDO can be changed by register setting No need to develop FW etc.
・Industrial grade compatible (-40°C to 105°C)
Operation verification of Power Sink is possible just by connecting the evaluation kit.
The BCR evaluation kit (CY4533) provided by Infineon can switch PDO in 5 stages with a rotary switch.
