MT7606 is a high-voltage single-segment linear constant-current LED driver chip with high output current accuracy and no EMI problem. The output current is flexibly set by an external resistor.

MT7606 integrates high-voltage power tube and high-voltage power supply circuit inside, and the peripheral circuit is simple. There is no need for magnetic components such as inductors or transformers outside the system, and EMI can be easily passed without additional components. The whole system is simple and the total BOM is low.

MT7606 has a good linear adjustment rate, which can achieve constant input power; in addition, MT7606 has a temperature adjustment function, which automatically reduces the output current when the chip temperature is too high, which improves the reliability of the system.

Features of MT7606:

? Simple peripheral circuit and low cost

? Good linear regulation for constant input power

? Built-in 500V power tube

? LED current can be flexibly set externally

? LED output current accuracy ±5%_? No EMI problem in chip application system

? Over temperature automatic adjustment function

? Adopt SOT89-3, TO252-3, ESOP8 package

MT7606 application:

? LED candle light, LED filament light

? LED fluorescent light, LED panel light

? LED bulbs, LED spotlights

? Other LED lighting products

Saiteng Microelectronics Co., Ltd. ("Saiteng Micro"), a chip and solution provider focusing on the automotive electronics field, recently announced that its main control MCU chip, ASM87F0812T16CIT, is tailored for automotive LED taillights and turn signals. It has passed a series of on-board tests and certifications from well-known domestic auto manufacturers, and has shipped over one million units. Saiteng Micro's successful development and mass production of this MCU signifies that the domestic MCU has achieved zero breakthrough in industrialization in the field of automotive front-mounted body control.

Saiteng Micro's ASM87F0812T16CIT is a high-performance dedicated MCU specially developed for automotive LED taillight control. <±0.3%) The dedicated circuit modules such as clock oscillator, edge capture PWM and highly reliable Data EEPROM make the LED tail light flow drive control more concise, the presentation effect is more perfect, and the synchronization visual recognition is more distinct.

ASM87F0182T16CIT has taken three years from chip design, film production, packaging and testing to solution development, debugging, and then on-board debugging and certification. Among them, various reliability tests (burn-in test, EMC test) are done to meet automotive-grade applications. and live temperature cycle test, etc.) for nearly a year. After a series of rigorous automotive-grade tests and verification to mass production, the cumulative shipments so far have reached 1 million.

In addition to car front-mounted taillights, Saiteng is also working with well-known car manufacturers to develop automotive breathing lights, ambient lights, matrix headlights and other application electronic control solutions. It is expected to achieve mass production in the second half of this year, and shipments will also be There are new breakthroughs.

Dr. Huang Jipo, general manager of Saiteng Micro, said that every process from the development and verification of automotive electronic chips to the procurement of OEMs is difficult. After repeated testing and verification, even if a product is found to be faulty, all links must be checked from beginning to end. , find the root cause and take effective solutions, the entire control process is quite strict, but Saiteng Micro has always been working hard towards the goal of localization of automotive electronics, and cooperated with partners in the upstream and downstream industry chains to finally keep the cloud open. See Moonlight. The company will take this opportunity to continue to develop the automotive "core" field. At the end of the year, we will also launch products in other application fields for the pre-installed automotive market.
