Electrification of automobiles is the trend of the times
In today's society, the automotive industry is undergoing unprecedented changes. With the continuous emergence of new technologies such as new energy and intelligent networking, automotive electrification has become the only way for the development of automobiles. The increasing complexity of automotive electronic systems places higher demands on the performance and reliability of electronic components.
The automotive electronic system is like a "brain", responsible for sensing, making decisions and controlling the functions of the whole vehicle. It includes multiple subsystems such as power electronics, body electronics, chassis electronics, information electronics, etc., each of which has a large number of electronic components. Taking the power electronic system as an example, it controls the powertrain such as the engine and gearbox, and requires a large number of power devices to achieve energy conversion and control.
Smart switches are indispensable key components in automotive electronic systems. It can intelligently manage the current in the circuit and protect the circuit from damage caused by abnormal conditions such as overcurrent and overheating, thereby improving the safety and reliability of the whole vehicle. The smart switch can also monitor the load current in real time and provide diagnostic data for the on-board computer, which helps to find and solve hidden faults in time.
The development of domestic intelligent switch products is lagging behind
For a long time, domestic smart switch products have been dependent on imports, mainly from internationally renowned manufacturers such as Infineon, Intel, etc. These multinational companies occupy a dominant position in the automotive electronics market by virtue of their first-mover advantage and technology accumulation. Due to the late start, there is a certain gap between domestic intelligent switch manufacturers and foreign products in terms of product performance and reliability.
Domestic intelligent switch WSD7025AD is proud
In the context of the lagging development of domestic intelligent switch products, the WSD7025AD dual-channel high-side intelligent switch independently developed by Wenxian Microelectronics Co., Ltd. has recently attracted wide attention in the industry. As an automotive-grade intelligent power device, it has many outstanding product features.
Dual-channel design with strong load capacity
WSD7025AD adopts a dual-channel design, with a load capacity of 7.5A and 5A per channel respectively, to meet the application needs of different power levels. Whether it's controlling a high-power seat heating system or a low-power light system, it can be easily controlled.
Ultra-low quiescent current, energy saving and environmental protection
The product's quiescent current is as low as 1.0μA, which significantly reduces the level of energy consumption. When the car is stationary for a long time, the intelligent switch will not cause excessive consumption of electric energy, which is conducive to improving the energy-saving and environmental protection performance of the whole vehicle.
High-precision load current detection, real-time diagnosis
WSD7025AD built-in high-precision proportional load current detection circuit, which can monitor the change of load current in real time, detect abnormalities in time and cut off the circuit, so as to protect the afterload from damage. This diagnostic data can also be read by the on-board computer for fault and prevention purposes.
Comprehensive protection function, safe and reliable
In order to ensure the safe operation of the whole vehicle, the WSD7025AD provides comprehensive protection functions such as over-current, over-voltage, under-voltage, and over-temperature. Once there is an abnormal situation in the circuit, the smart switch will automatically cut off the circuit to avoid the occurrence of dangerous situations.
Domestic smart switches ushered in spring
The advent of WSD7025AD marks a major breakthrough in domestic intelligent switch products and a new stage in line with the international advanced level. This not only injects new impetus into the development of the automotive electronics industry in the mainland, but also promotes the upgrading of the entire automotive industry in the direction of intelligence and electrification.
Improve the localization rate of automotive electronic products
For a long time, the localization rate of automotive electronic products in mainland China has been low, and a large number of key components rely on imports. As the core component of the automotive electronic system, if the intelligent switch can be replaced by domestic production, it will greatly improve the localization level of the whole vehicle, which is conducive to reducing production costs and enhancing industrial competitiveness.
Contribute to the process of intelligent and electrification of vehicles
Intelligent and electrified vehicles are the only way to develop in the future. As the "brain" of power control and management, smart switches play an important role in this process. The breakthrough of domestic intelligent switches will provide a solid hardware foundation for the application of new automotive technologies.
Call for increasing investment in domestic smart switches
Although gratifying progress has been made WSD7025AD, compared with the international advanced level, there is still a certain gap in the technical strength and product line richness of the mainland's intelligent switch products. It is necessary for us to further increase the investment in the research and development of domestic intelligent switches to promote the rapid development of the industry.
Only by constantly innovating can the mainland's intelligent switch products occupy a place in the future market competition and contribute more domestic strength to the intelligence and electrification of the automotive industry. Let's wait and see the next breakthrough of domestic smart switches!
