Jiangsu Diao Microelectronics Co., Ltd. is an integrated circuit design company specializing in the R&D, design and sales of high-performance analog chips. The core management team comes from Fairchild Semiconductor, all with more than fifteen years of experience. working experience. Diao Micro's products are mainly divided into two series: signal chain analog chips and power management analog chips, which are mainly used in automotive electronics, consumer electronics, communication equipment, industry and medical equipment and other fields.
Diao Micro (stock code: 688381), as one of the top ten analog chip companies in domestic IC design, has always had a number of core technologies in smart lighting and occupies market advantages. In recent years, the company has increased its investment in R&D in the field of automotive electronics. Thanks to its strong R&D strength, it has developed a number of cutting-edge products for body lighting, which have been widely recognized and supported by customers.
Core product DIA89360
DIA89360 is an automotive-grade 60V four-switch synchronous buck-boost controller with an efficiency of up to 96%. It can support both constant current and constant voltage modes. It can provide complete fault diagnosis and protection functions and supports analog and digital (built-in & external Set) dimming function, the switching frequency is adjustable and supports spread spectrum function. Its built-in PMOS driver can also be used to expand high dimming ratio applications.
In addition, a single DIA89360 can drive multiple output channels. Compared with traditional single-channel driving solutions, it has the advantages of fewer peripheral components, low BOM cost, high efficiency, and good EMC performance. It is especially suitable for automotive headlight high and low beam lighting systems.
Car-grade 60V multi-topology headlight controller DIA82901
DIA82901 is a very flexible DC/DC controller with rich built-in diagnostic and protection functions. A variety of power topology architectures can be realized by simply adjusting external components, and each topology supports two modes: constant current/CC and constant voltage/CV.
The built-in pulse width modulator can easily realize the dimming function to reduce color shift, and includes a spread spectrum modulator to improve EMC performance; the current mode control used can achieve a stable regulation loop through a simple compensation circuit; the built-in The soft-start function effectively limits current spikes and voltage overshoots at startup.
12-channel pixel-level taillight high-side driver solution DIA82920
DIA82920 is a 12-channel linear taillight driver solution with superior EMC performance. Each channel can be controlled independently, and the single-channel current is up to 100mA. The device integrates a UART interface with a transmission rate up to 2MHz, and CAN communication can be easily achieved by adding an external CAN transceiver. It has built-in complete diagnostic and protection functions, in which the open circuit and short circuit of the LED light string can be detected in real time. Built-in programmable EEPROM allows customers to flexibly configure different application scenarios.
On May 16, 2024, the 5th Intelligent Car Lighting Innovation Technology and Supply Chain Forum organized by Chongqing Automobile Club and Aibang Smart Car Club will be held at Chongqing Jinling Hotel.
