Jinzhou 777


Jinzhou 777 Microelectronics Co., Ltd. traces its origins to the state-owned 777 Factory, a specialized semiconductor plant with over 50 years of manufacturing history. It was among the first batch of nationally recognized designated production facilities for analog integrated circuits. Today, the company operates three dedicated production lines: a monolithic analog IC line, a hybrid IC line, and a microcircuit module line. The monolithic analog IC line primarily produces more than 100 product varieties, including operational amplifiers, voltage comparators, timing circuits, voltage references, and integrated regulators, with an annual mass-production capacity of 600,000 units. Meanwhile, the hybrid IC line boasts an annual output capacity of 50,000 units, while the microcircuit module line can produce up to 20,000 modules per year.

Zhongwei Aixin: Releases the Three-Phase PNMOS Gate Driver AiP4480

Gate drivers are critical core components in power conversion and motor control systems, serving as a high-speed, reliable interface between the control signals and the power MOSFETs or IGBTs. In power electronic systems—whether in new‑energy vehicle drive controls, photovoltaic inverters, industrial variable‑frequency drives, or motor control systems—their performance hinges on the precise control provided by gate drivers.
