With the increase of battery capacity and density (battery serial parallel structure), the application scenarios of lithium batteries (batteries) are also increasing, involving some application scenarios such as consumer, industrial, and high-power batteries.For example, when it reaches 4 series of lithium batteries, it can be used as a 100W two-way mobile power supply; when it reaches 3 to 6 series of lithium batteries, it can be used as a battery pack for electric tools; when it reaches more than 12 series of lithium batteries, it can be used as a battery pack for electric bicycles; as the number of series increases, it can be used as a larger energy storage product.
The new energy system structure of lithium battery includes battery pack, PACK, lithium battery protection, power metering, optional DC/AC, DC/DC, and system status display. With different battery capacities, relevant functional modules are cut or merged.
Applicable scope of PD DRP high power products.With the popularization of Type-C interface of electronic products and the increase of industrial electric equipment, the market of (medium) high-power mobile power supply is also expanding;With the increase of electric tools, the corresponding demand for battery packs is also growing;Small energy storage products such as consumer electronics and industry are also constantly updated and iterated;The application of new equipment and built-in batteries will also increase the range of PD DRP high-power products.
In order to adapt to the above expanding market, Guangzhou Microelectronics Co., Ltd. launched PD Plus SoC chip architecture, PD DRP bidirectional power transmission, continuously expanding high-power (240W), complex power management, complex power distribution strategy, optional electricity meter function, optional digital display function, scalable communication interface and other characteristics of PD chips.
Details of PD Plus SoC chip - UM3506 series.The chip adopts a TCPM/TCP/TCC hierarchical architecture, which allows multi port expansion, and integrates a native TCP like front-end module, including digital logic and analog circuits for Type-C interface detection and control, packet BMC codec of PD PHY layer, and key functions in PD protocol layer that have strict requirements for timing.
It supports multiple interfaces and protocols, and multiple modes that meet the specifications of PD3.1 and PD3.0. It has a complete PD protocol library that supports continuous upgrading and flexible expansion. The full-featured SRC/SNK/DRP can customize differentiated system strategies and adapt to applications of multiple products.
The wide core micro UM3506 series has built-in high-performance 32-bit MCU microprocessor core, large capacity Flash memory, SRAM memory, enhanced peripheral interface and rich system resources;Support 6-channel enhanced PWM function (2xfcpu);12bit SAR ADC, up to 16 channels;Current detection and other safety functions;Integrated TL431 (UM3506-S24QA proprietary);Support wide 3.3-24V VBUS power supply.It also supports low power consumption mode and Free RTOS operating system.It is convenient for the smooth operation of the chip under multi task operation, and meets the customized requirements of manufacturers.
The UM3506 series of PD Plus SoC chips not only support multiple interfaces and protocols, but also meet multiple modes of PD3.1, PD3.0 and other protocols.There is also a perfect development ecology, RISC-V IDE, chip burning software, chip offline burner, open platform architecture, combination of software and hardware, and application library support for continuous expansion.Through the powerful UM3506 open source system architecture, it can meet the customized and differentiated customization needs of manufacturers and facilitate their debugging and application.
One of the characteristics of the PD chip UM3506 product, two weeks after the launch of the PD 3.1 standard, the original product's PD 3.0 standard was upgraded to the PD 3.1 standard through software, and SRC,SNK, DRP and E-MARK support the whole system, support PD3.1 EPR 240W and backward compatible PD3.0 SPR 100W, also support PD3.1 EPR AVS dynamic voltage application, as well as the Chunk sending of extended messages and the long packet sending mechanism of 260Bytes. It has flexible VDM message expansion capability.
The first DC-DC conversion modular solution of PD system solution, the application solution of 1C1A charger, also supports the single C port design, the C port supports 5/9/15/20V/28V and PD3.1 or higher power upgrade, the two-way 100W/140W function of the C port, also supports the traditional A port, the optional coulometer power, nixie tubeOLED, LCD drive screen, northbound communication interface and other functions meet the different needs of charger manufacturers.
DC-DC conversion modular solution II, application solution of 2C2A charger.Any C port has two-way 100W/140W function, and any port can be filled while being placed.After the adjustment of the system strategy, it supports dual chargers to charge the power bank at the same time, and automatically selects high-power chargers for charging.
The above are the first three cases of the application of the wide core micro application scheme in the world's 100W high-power PD/Type-C mobile power supply.
The above is the application case of the 140W PD3.1 mobile power supply/energy storage of Guangxin Microelectronics. The voltage can be expanded to 5~48V by using the 5~7 series of cores. The maximum 240W power has been commercially available.The application scenarios are mainly high-power mobile power supply and PES portable energy storage.
The above is the application case of Guangxin Micro in electric tools. The demand for battery packs of electric tools in the market is still very large.The matching scheme of 3~6 strings of battery cells of Guangxin Micro and the scheme of converting small boards/built-in battery packs enable the battery packs to support DRP bidirectional 45W/65W/100W, PD3.0 to PD3.1 (28V/36V/48V etc.), Max.240W.It is not only convenient for users to charge, but also can improve the charging speed, or become a mobile charging bank to provide charging for other devices. Traditional electric tool chargers have poor interface compatibility, large size, and are inconvenient to carry.It is applied to battery pack conversion accessories or battery pack standard interface.
The above is the application case of wide core micro in small energy storage. It supports 4-7 series lithium battery solution, overall MCU management and LED/LCD digital display function.In addition to small energy storage products, it can also be applied to Ethernet combined POE, luggage and luggage.
The above is the wonderful speech of "Introduction to the Two way High Power Application of Guangxin Micro PD" by Guangxin Microelectronics (Guangzhou) Co., Ltd., which insists on creating cores for low-power networking.
