Chinese manufacturers break industry record: 9 fast charging power supply protocols for single chip integration

Release date：2017-07-15   Views：2019

Last year, SMIC won a number of honors with the popular ip5318 model, such as the first multi in one fast charging mobile power chip with dual certification of Qualcomm qc2.0 and qc3.0, the fully integrated fast charging mobile power chip with the highest shipment volume, and the power chip for power bank fast charging adopted by the most top tier brands. Yingjixin ip5318 frequently appears in the dismantling reports of well-known powerbank brands, and obtains market recognition with the most realistic shipping data.

After continuing to achieve market success of ip5318, SMIC updated and released the latest version of ip5328 after collecting user feedback and the current fast charging application trend. It is reported that ip5328 is expected to upgrade to support qc4 + in the future.

SMIC ip5328 is a multi-functional power management integrated with qc2.0 / qc3.0 output fast charging protocol, FCP / AFC / SFCP I / O fast charging protocol, MTK PE + 1.1 & 2.0 I / O fast charging protocol, USB C I / O protocol, compatible with bc1.2/apple/samsung mobile phone, synchronous up / down converter, lithium battery charging management, battery power indication and other multi-functional power management SOC provides a complete power solution for fast charging mobile power supply. It can support USB a X2, USB B and USB C at the same time. Any single USB port can support fast charging. When two or more output ports are used at the same time, only 5V is supported.

With high integration and rich functions, yingjixin ip5328 only needs one inductor to realize the function of step-down and boost, so that it only needs few peripheral devices in application, and effectively reduces the size of the overall scheme and reduces the cost of BOM.

Ip5328 has built-in USB C protocol, which can support USB C port input high current charging and output high current discharge. Ip5328 has built-in 14bit ADC, which can accurately measure battery voltage and current, and can access ADC data through I2C. Ip5328 built-in power calculation method can accurately obtain battery power information. The battery power curve can be customized to accurately display the battery power.

Ip5328 has built-in power MOS, and the synchronous switch boost system can provide a maximum output of 26W, which is the industry leader in ultra-high efficiency. Even when the battery voltage is low, the output of 18W can still maintain more than 90% efficiency. When it is empty, it will enter into sleep state automatically. Ip5328 synchronous switch charging system provides charging current up to 5.0 a. Built in IC temperature, battery temperature and input voltage control loop, intelligent regulation of charging current.

Ip5328 supports 1 / 2 / 3 / 4 LED power display, intelligent recognition of power display mode, support lighting function, support button, charging and discharging need to be customized. According to the customer's personalized customization requirements, the original factory of yingjixin also provides I2C interface, which can flexibly customize screen display, nixie tube and other functions.

The high-speed charging technology of Qualcomm qc4 + that you are most concerned about. After consulting with the engineers of SMIC, ip5328 is expected to upgrade to support qc4 + in the future.
