Hynetek Launches PD3.1 140W Dual C-port Fast Charging Solution

With the introduction of the PD3.1 standard, there is a breakthrough in maximum fast charging power, from 100W to 240W, and its application market expands to portable devices, IoT devices, smart home, communication and security devices, automotive and medical. We look at USB PD3.1 with a long-term perspective, it will be a change and evolution of up to 3 to 5 years and more. The first devices to support USB PD3.1 are Apple's 2021 Macbook Pro, which supports 140W of USB-C fast charging. Facing this demand for more than 100 watts of fast charging, Hynetek has launched a 140W dual C-port fast charging source solution, which is realized by two HUSB311s.

Application

HUSB311 is a USB Type-C PD controller chip that complies with the latest USB Type-C and PD3.1 standards and can support PD3.1 commands such as PPS, EPR, etc. It supports 140W (28V/5A) power supply and power extraction. It can be configured as PD3.1 Source only, PD3.1 Sink only and PD3.1 DRP.

Evaluation board with HUSB311

    The program Buck choose MP8880, the protocol chip using two HUSB311 support PD3.1 fast charging protocol, the overall design peripheral streamlined. The following figure shows the design schematic of the program.

   This solution supports 140W power fixed or dynamic shared dual USB PD outputs. hUSB311 has two I2C addresses, and the embedded controller can use one I2C bus to communicate with two HUSB311s.
