With precise power control and lightweight design, the NOVOSENSE NSE34/35 series smart high-side switch delivers innovative solutions to advance the automotive industry’s green transformation. It effectively prevents unnecessary power consumption by dynamically adjusting the load current and its switching states. For example, in the case of lighting systems, lights can be automatically adjusted, and any idle lights can be turned off according to ambient light levels, significantly improving the utilization of electric energy and reducing energy consumption by vehicles. Its highly integrated design replaces traditional fuse and complex wiring, reducing the harness length by more than 30%, and helping to reduce vehicle weight and extend the driving range. At the same time, the chip has built-in protection mechanisms for overcurrent, overvoltage and short circuiting, and it is equipped with real-time diagnosis functions, which cut off the circuit in milliseconds under abnormal conditions, effectively safeguarding against potential safety hazards caused by electrical failures. With its power efficiency, light weight and safety features, the NSE34/35 series is accelerating the automotive industry’s transition towards low-carbon and intelligent development.
With the help of precise sensing technology, NOVOSENSE’s NSPGL1 differential pressure sensors and NSPAS5N absolute pressure sensors deliver emission control optimization for modern vehicles. NSPGL1 is specially designed to monitor fuel vapor pressure and detect crankcase ventilation leaks. It realizes ± 2.5% F.S. high accuracy across a wide temperature range of -40℃ to 130℃ , effectively helps carmakers meet Phase VI emission standards, and reduces pollutant emissions from fuel evaporation. Meanwhile, NSPAS5N is designed for exhaust gas treatment systems. With its corrosion resistant design and ability to respond within sub milliseconds, this sensor accurately detects the pressure of intake manifolds within a pressure range of 10kPa-400kPa, optimizes combustion efficiency and improves fuel economy by 8%. By engaging in real-time data-based closed-loop control, the two sensors work together to reduce emissions of NOx and other harmful substances in exhaust gas, providing reliable technical support for automotive enterprises to meet increasingly stringent environmental regulations.
Due to the strict high-voltage safety standards in the photovoltaic industry, traditional opto-coupler isolation is widely used across a variety of scenarios. However, opto-coupler isolation has inherent defects, such as high energy consumption and a short lifespan, which limits the overall performance and reliability of photovoltaic systems. To address this pain point, NOVOSENSE has launched an innovative gate driver solution based on capacitive isolation technology, represented by the NSI6801 and NSI6801E series products, breaking the limitations of traditional opto-coupler solutions. This product series features strong driver capabilities, high common mode transient immunity (CMTI), low delay and other technical advantages. These products have been certified under the VDE enhanced isolation safety standard, and they are being widely used in DC-AC solar inverters, UPS and battery chargers, and isolation DC-DC and AC-DC power supplies. The NSI6801 series enables photovoltaic systems to meet high-voltage safety standards while minimizing operational and maintenance costs. These advantages help enhance system longevity and efficiency, driving the industry toward greater sustainability. With this technological breakthrough, we have injected new momentum into the green energy transformation of the photovoltaic industry.
NOVOSENSE has introduced an innovative product that uses a higher bandwidth current sensor to help customers monitor higher frequency current signals. This feature helps customers adopt higher switching frequency system designs, thereby improving the overall power density at the system level and further reducing the system size.
The key application of the product is OBC for new energy vehicles. As the size of OBC/DC-DC/PDU shrinks, the mutual interference between electronic components becomes more serious. To address this challenge, our product has been comprehensively improved in terms of anti-interference performance. This performance improvement can help customers adopt a smaller design, reducing the overall PCB size by at least 20% and thereby further minimizing the use of PCB raw materials for the product.
NOVOSENSE is developing an innovative isolated op amp with integrated isolated power supply, which is specially designed for server power supply. It can help customers' systems improve sampling accuracy at 10% load, reduce overall system power consumption through higher precision system control, and ultimately achieve the goal of system efficiency of more than 90%, and can help customers' server power supply products achieve the 80Plus Titanium certification.
At the same time, the product's integrated isolated power supply design is also conducive to customer system miniaturization.
NOVOSENSE regulates the use of energy and resources and strives to build ourselves into a resource-saving and environment-friendly company.
