With the popularity of wireless charging of mobile phones and TWS headphones, more and more portable devices support wireless charging. Wireless charging to put and charge, no need to plug in, and the charging speed and wired charging are comparable to the advantages, won the favor of the majority of manufacturers, but also for users to bring the use of experience to improve.
Nanxin launched a fully integrated third-generation wireless charging transmitter CHIP SC9608, as a highly integrated wireless charging SOC, SC9608 internal integrated fast charging protocol, Power Stage and MCU master control and other wireless charging must be used, only external simple devices can achieve a complete wireless charging design, can be compatible with 15W and below wireless charging TX applications. The SC9608 integrates a 32-bit high-performance MCU with rich IO and large memory. Can be combined with SC5001 Power Stage, support a wireless charging chip plus a Power Stage, to achieve two independent wireless charging control.
Shanghai Nanxin Semiconductor Technology Co., Ltd., founded in Shanghai Pudong Zhangjiang Hi-Tech Park, is a high-performance domestic semiconductor design company focusing on power supply and battery management, with Charge pump, DCDC, ACDC, wired charging, wireless charging, fast charging protocol, lithium battery protection and other product lines, based on independent research and development of buck-boost charging, charge pump and GaN direct drive and other core technologies, launched a variety of star products, widely recognized in the industry.
Nanxin can provide an end-to-end fast charging complete solution from AC to battery, covering the entire range of 10W to 200W. Among them, the charge pump high-power fast charging series of products has taken the lead in breaking the monopoly of foreign countries, passed the strict certification of many well-known domestic brand mobile phone manufacturers, and has achieved large-scale stable mass production.
The picture shows the one-core dual-charge wireless charging model of the SC5001 wireless charging chip of The Southern Core SC9608. Sc9608 supports 15W wireless charging transmitter module at the same time, its rich kernel resources, can synchronously drive AFE SC5001 to complete the wireless charging of the extended transmitter module.
The actual test of the one-core double charging model of the Nanxin SC9608+SC5001 can add a wireless charging while supporting the two choices of two coils, which can meet the wireless charging needs of vertical mobile phones + watches/headphones at the same time.
Nanxin SC9608 wireless charging transmitter chip integrates Power Stage, high-performance MCU and fast charging protocol functions. The traditional fast charging input wireless charging multiple chips are integrated into one chip to achieve all functions.
The SC9608 supports 4-14V input voltage, a built-in 32-bit digital core, rich memory and peripherals, WPC V1.2.4 EPP and BPP, and proprietary wireless charging protocols. The SC9608 is available in a 4*4mm, FCQFN-25 flip-pack package for better thermal performance. Suitable for WPC-compatible wireless charging transmitters and proprietary protocol wireless charging transmitter applications, enabling simplified highly integrated wireless charger designs.
The start-up team of Nanxin comes from well-known European and American semiconductor companies and has rich industry and product experience. The company has a strong R & D and system team, an independent quality control team, and a sales and support team close to customers, escorting high-quality product development and design. Nanxin has also been widely recognized by the upstream and downstream industry chains and capital, and has received support from Xiaomi, OPPO, VIVO, SMIC Juyuan, Shanghai Integrated Circuit Industry Fund and Sequoia Capital, which greatly helps the company's sustained and rapid growth and reliable supply guarantee.
Nanxin SC5001 is an integrated power full-bridge power stage chip with built-in voltage and current demodulation, supporting 4-14V supply voltage and supporting up to 15W output power. Can be used in combination with a microcontroller or in conjunction with sc9608. SC5001 internal integrated power full bridge, drive stage and bootstrap circuit, internal integrated 5V voltage regulator circuit for external MCU power supply, chip internal integrated input voltage protection, overcurrent protection, short circuit protection, overtemperature protection, using 3 * 3mm QFN19 package. High level of integration saves PCB area occupation.
