About 2Pai Semiconductor

2Pai Semiconductor (Rongpai Semiconductor) is a fabless semiconductor company based in Shanghai, China. Founded in 2017, the company designs and develops high-performance analog and mixed-signal integrated circuits, with a strong specialisation in galvanic isolation products. The core of 2Pai's portfolio is digital isolators, sold under its π-series part numbers, alongside isolated gate drivers, isolation amplifiers, isolated interface ICs and related analog devices such as amplifiers, data converters, driver ICs and optocoupler replacements. These products provide safe signal and power separation between high-voltage and low-voltage circuit domains, a requirement in modern power conversion and control systems. 2Pai's devices are used in electric vehicles and charging infrastructure, solar inverters and energy storage, industrial automation, motor drives and power supplies, where isolation performance, noise immunity and reliability directly affect system safety. As a domestic Chinese supplier of isolation ICs, the company has become an important alternative source for designers and OEMs seeking to diversify their supply chains. 2Pai Semiconductor's products are available through authorised distribution channels internationally, making it accessible to engineering teams in Europe, India and other markets looking for competitive isolation and analog IC solutions for electro-mobility and power electronics designs.
