GaoteIt has gone far in the field of USB-C special ESD protection chips for fast charging. At present, it has 13 basic, 8 advanced and 5 innovative products, and a total of 26 different models of USB-C special ESD protection chips for fast charging.These products cover all levels from entry level to high-end market, and can meet the needs of different users.At the same time, Gaote also pays attention to product development and innovation, and constantly introduces new products and technologies to provide users with better solutions.
Basics
The ESD protection chip of Gaote is mainly aimed at the entry-level market, which is characterized by low cost and easy integration.These chips can provide reliable ESD protection at a lower cost through optimized design.At the same time, they also have smaller volume and weight, which is convenient for users to use in various application scenarios.
The working voltage range of the single tube ESD protective device in the basic chapter of Gaote is 5V~24V, and the SOD-523SOD-323 and DFN1006 are three kinds of package shapes. When manufacturers select the protective devices for the single tube ESD protection scheme in the basic chapter of USB-C fast charging, they can select the above 13 different ESD protective devices according to different needs to achieve the best protection effect and the manufacturers' requirements for volume and heat dissipation.
Advanced
The ESD protection chip of Gaote is mainly aimed at the middle and high-end market, with higher performance and richer functions.These chips adopt more advanced process technology and more refined design to provide higher ESD protection capability and lower power consumption, and can be applied to more USB-C fast charging products to meet the charging requirements of different devices.
The traditional single tube ESD protection scheme is made into a four in one scheme, that is, four single tube ESD are integrated into one ESD protection device, and one ESD device can meet the protection of four lines.Inspired by the power density requirements of the power supply board of an outdoor small base station of Huawei, whether the original four ESD single tubes can be sealed, eight SOT-23-6L packaging products with the four in one solution have been developed.The advantages are higher power density and higher surge resistance.
Innovation
The ESD protection chip is the latest research and development achievement of the company, mainly for high-end markets and special application scenarios.These chips adopt new design concepts and technical means to achieve higher performance and lower power consumption.At the same time, they also have stronger anti-interference ability and higher reliability, which can meet the use requirements in various harsh environments.
The five ESD protective devices in the innovative scheme of Gaote PD fast charging electrostatic protection all adopt the DFN2510 package, which has smaller board area, simpler wiring mode, lower component cost, and fewer times of placement.The pin spacing of this package is very close to the pin spacing of Type-C interface, which can realize straight through wiring.Therefore, the ESD protective devices in this scheme can be placed as close as possible to the Type-C interface. The straight through wiring method shortens the circuit between the ESD protective devices and the protected lines and ground wires, thus reducing the chance of self inductance coupling to other adjacent lines.
