More than 20 domestic analog IC strength competition, who will lead?

Compared with digital chips, analog chips have the characteristics of high signal-to-noise ratio, low distortion, low power consumption, high reliability and stability. The life cycle is often more than 10 years, and the application fields are wide and the price is relatively stable. It is not easy to be affected by a single industry boom. degree of influence. According to data from IC Insights, a research institute, the scale of China’s analog chip market reached US$23.5 billion in 2019. Among them, the domestic output value is much smaller than its market size, and there is huge room for import substitution.

In recent years, with the gradual expansion of the analog integrated circuit industry market, my country’s analog IC manufacturers are slowly rising. At the same time, it is necessary to increase investment in research and development, aiming to catch up with the international advanced technology level, fill the gap of domestic high-end analog chips, and reduce my country’s analog IC manufacturers. The gap between integrated circuits and the international advanced level will gradually get rid of the dependence on foreign imported products and patented technologies.

The selection activity of “2020 Hard Core China Chip”, sponsored by Chip Master, branded by Shenfubao Group, and sponsored by Mouser Electronics with exclusive gifts, commends domestic excellent semiconductor companies and encourages domestic companies to increase their efforts in IC product and technology research and development. Among them, there is the “2020 Domestic Analog Circuit Chip Selection”, and the annual blockbuster products have participated in the competition.

This article will take stock of more than 20 participating products in the “2020 Domestic Analog Circuit Chip Selection”. (The following content is in random order, in no particular order.)

Domestic high-power, high-efficiency, and cost-effective wireless charging chips are compatible with wireless charging applications of various standard powers such as 5W/7.5W/10W/15W and 20W.

Product introduction:

1. Product performance: THP9330 series product is a high-power, high-efficiency wireless charging receiver chip that conforms to the Qi standard. The chip integrates a high-efficiency synchronous rectifier circuit and an LDO circuit. The output power is up to 20W, providing a programmable voltage output of 5~15.6V. The internal design of the position alignment circuit can be used to indicate the alignment between the transmitter and receiver coils. In order to achieve the best coupling effect, an overall more efficient charging solution can be provided for different application scenarios.

At the same time, comprehensive and effective protection mechanisms such as overvoltage, overcurrent, and overtemperature can also keep the system in a safe and optimal working state. With fewer peripheral devices, an efficient and complete wireless charging receiver solution can be built. The core performance indicators of this series of products have reached the level of similar international competing products, and have been recognized in the field of non-mobile phone applications. The evaluation of mobile phone manufacturers is also underway, and it is expected to enter the mobile phone supply chain in the future and complete the domestic substitution in the field of wireless fast charging chips.

2. Price competitiveness: Compared with similar products, the overall cost performance of the product is very high.

3. Technological innovation: The MOS synchronous rectification technology used in the THP9330 series enables the coil AC input to the chip DC output efficiency to reach 95%, and the loss is extremely low. It is a high-efficiency wireless energy transmission system;

THP9330 series chips are compatible with wireless charging applications that support QI protocol for various standard powers such as 5W/7.5W/10W/15W and 20W. During use, the internal logic of the chip can adjust the voltage and power output state according to the transmitter settings to achieve expected power conditions. When the chip detects that the transmitter does not have high-power transmission conditions, it will automatically adjust to the low-power transmission state that the transmitter can receive, and does not need to be reset. At the same time, the chip can support various wireless transmission private protocols to ensure high compatibility;

The THP9330 series chip supports the foreign object detection (FOD) mechanism in the wireless charging process. During the wireless charging process, the chip can accurately calculate the actual power consumption and estimate the energy lost in the air for wireless charging. In this way, when a metal or similar object enters the charging field by mistake, the vortex energy loss energy generated by it can be obtained by subtracting the actual consumption and air loss from the transmitted energy. When this is detected, the system shuts down the wireless charging process to ensure that metal or similar objects do not become hot due to electromagnetic fields and create possible safety issues. Combined with its own complete overvoltage, overcurrent, overtemperature detection and protection shutdown mechanism, different from the traditional wireless charging and receiving system without FOD mechanism, THP9330 series chips can ensure that the wireless charging process is always in a safe and reliable condition.

4. Customer service: The company has reached cooperation with domestic mainstream manufacturers to provide high-quality products and services for many international first-line brand customers, and output high brand influence and brand value.
