Sensylink

Sensylink Microelectronics Inc. operates as a fabless semiconductor design company with a sharp focus on high-performance sensor and mixed-signal chips. Founded in Shanghai in February 2015, the company was established by a team of returnees from Silicon Valley and local Chinese experts, including Chairman and founder Lai Jianwen and co-founder Wang Yu. Wang Yu holds a Master's degree in Microelectronics from Fudan University and previously managed product marketing at Shanghai's BCD Semiconductor, which was listed on NASDAQ. This blend of international experience and local market knowledge underpins the company's strategy.

The firm's business model revolves around the design, development, and sale of its proprietary integrated circuits (ICs), which are then manufactured by partner foundries. Sensylink serves a diverse client base across industrial, automotive, communications, and consumer electronics sectors. Its products are embedded into a wide array of final goods, including computers, servers, security systems, smart home appliances, electric vehicles, and wearable devices. The company generates revenue through the volume-based sale of its chips to these equipment manufacturers.

Sensylink's product portfolio is extensive, boasting over 500 products with independent intellectual property rights since its inception. Key offerings include a variety of environmental sensors—such as those for temperature, humidity, and ambient light—alongside interface ICs, security chips, and general-purpose analog-to-digital converters (ADCs). A notable product is the CHT8315, a digital sensor providing temperature readings with an accuracy of ±0.5°C and humidity readings at ±3.0%RH. Another example is the CAD2726, a current and power monitor with an I2C interface designed for laptops and battery chargers. The company's core technology combines novel transducer designs with optimized ADCs and proprietary calibration algorithms for mass production. This has led to significant milestones, including releasing its first temperature sensor in 2016, achieving annual revenue over 100 million RMB in 2021, and shipping a cumulative 500 million ICs by the fourth quarter of 2022.
