Released three-mode wireless charging chip, combined with high-pass Xiao Long platform put into use
As we all know, WPC and Air Fuel is the wireless charging market two standard alliance, the latest iPhone 8 series wireless charging is the use of WPC Qi standard, Qi standard is also the mainstream of the wireless charging market standards.But Air Fuel Union standards based on magnetic resonance technology, In the 'empty' wireless charging experience will be better and long-term optimistic about the industry, the standard leader is Qualcomm.
Recently, Xi Di Microelectronics said that Xi Di micro is working with Qualcomm in the field of wireless charging in-depth cooperation, the development of three-mode wireless charging chip HL6101 will be in the follow-up high-pass Xiao Long ™ mobile platform put into use, HL6101 will be Qualcomm 2018 mobile phone platform only reference design.As a wireless charging WPC and Air_Fuel two major members of the Union, Xi Di microelectronics latest integrated three-mode high-power wireless charging receiver chip HL6101, to achieve the WPC and Air_Fuel model of full compatibility and Automatic identification, and supports up to 15W output power.
It is understood that, as a fully integrated wireless charging receiver chip, the Greek micro-HL6101 fully compatible with the automatic identification of WPC V1.2 (Qi) and Air_Fuel standards. The chip not only integrates a high efficiency of the full-synchronous rectifier and high-performance switch stability And supports 4-12V output voltage and up to 15W output power, providing industry-high conversion efficiency.
Easy to integrate into the mobile phone motherboard, is expected to continue to import mobile phone customers
With the mobile phone function more and more, more and more battery capacity, mobile phone motherboard is getting smaller and smaller, try not to change the internal structure of the existing mobile phone at the same time, it is not easy to integrate the wireless charging chip PCB board. However, the HL6101 is a highly integrated wireless charging receiver chip that optimizes and streamlines many peripheral devices and can be easily embedded in the smartphone's motherboard with high design flexibility while matching different coil designs and adjusting outputs Voltage to meet the different input voltage specifications of the lithium battery management charge chip.
In the detection receive mode, HL6101 chip by optimizing the full synchronous rectifier operating conditions to achieve optimal efficiency, which is more prominent feature is the use of high efficiency switching regulator instead of the traditional low dropout voltage regulator (LDO) to enhance the charging efficiency , So that the chip can accept a wide Vrect voltage input, with a wide Vout output voltage, and can maintain a high power conversion efficiency.
In the package, HL6101 WLCSP and QFN, respectively, two packages, WLCSP package with 64-bump, 0.4mm pitch, QFN package with 32-pin 5mmx5mm. The chip can support a variety of 1-2 lithium battery wireless charging applications, Widely used, can be used in smart phones, tablet PCs, laptops and rechargeable Po and other accessories and other fields.
At the same time, HL6101 supports multi-mode wireless charging and receiving solution Fully compatible with WPC (Qi) and Air_Fuel, and integrated multiple protection, for input overvoltage, output overload, over temperature and other abnormal circumstances, to ensure safe operation in all applications, This will give users a better experience.
Nowadays, in the iPhone8 series, now including millet, Huawei, Jin Li, hammer, Nubia, glory, VIVO and other domestic mobile phones have been carried out radio charging products pre-research, next year there will be a lot of wireless charging mobile phone market. As a simulation of integrated circuit design company, its production of fast charge, power metering and efficient power conversion chip products are already mobile devices, accessories and other battery applications, the core component of the new launch HL6101 wireless charging chip At the same time, in the high-pass blessing, HL6101 will be in the high-pass Xiaolong mobile platform put into use, is expected next year is expected to continue to import more mobile phone customers, snatch the wireless charge 'big', the mobile phone manufacturers have been optimistic and carried out pre-research.
