eEver Technology, Inc. and Etron Technology, Inc (TPEx: 5351.TW) announce that their joint development product, USB PD3.0 controller IC－EJ899, hugely boosts efficiencies in delivering power, transmitting data, and streaming audio and video within USB Type-C solutions. USB PD3.0 provides voltage and current and transmits communication using new specifications, enabling fast charging, flexibility and low power consumption. The EJ899 can deliver power of 100 watts at maximum and up to 5 Amps at 20 Volts, and also allows two-way power delivery between the power provider and consumer, creating a high degree of flexibility and ability to optimize power management. The EJ899 is suitable for USB 3.1, USB 3.0, and USB 2.0 interfaces and other USB specifications and can be widely used in all sorts of electronic systems and devices with charging functions.
Etron’s USB Type-C PD3.0 controller IC design solutions are fully compliant with USB-IF’s latest USB PD3.0 specification. The general efficiency of PD3.0 is improved compared to PD2.0. For data transmission, whereas PD2.0 supports transmitting of only 28 bytes at most, PD3.0 supports up to 260 bytes, enabling transmitting more messages, for example: manufacturer information, security information, firmware update information, etc. For the data delivery process, whereas PD2.0 cannot transmit smoothly in the event of a sudden disconnect of its power source, PD3.0 can switch the role of power provider and consumer and can prevent data corruption during a sudden disconnect of its power source. Moreover, Etron’s USB Type-C PD3.0 controller IC is fully backward compatible with USB PD2.0, enables faster performance for firmware updates, unleashes highest power efficiency and adds a certification information switching function between Type-C and cables.
