Prolific was founded in 1997 with a vision that USB would be the standard I/O interface for the new generation PC and Peripherals. Since then, the Company has strived for research and development of high performance USB transmission standards that will identify Prolific as a Total USB Solution provider. Currently, Prolific provides USB Full-Speed, High-Speed and Super-Speed total solutions for three product categories: UART/RS232/Serial/Printer, Storage and Connectivity.

Power IoT

The energy industry from power generation to power consumption is undergoing a green revolution. Green appliances need monitoring and power management, as better measurement and management leads to better conservation and waste reduction. Prolific offers a range of cutting-edge SoC solutions providing high accuracy, high integration, and simplified design, while giving manufacturers highly reliable solution at a lower BOM cost.

FxH (Fan & Hall)

Mixed-mode technology integrates analog and digital circuits into a single IC solution. It combines features from both technology and provides high stability and easy control.

Prolific Technology offers a wide range of MEMS (micro-electro-mechanical systems) products utilizing Mixed-Mode techniques. Products include magnetic sensors, Hall effect sensors, motion recognition, motion sensing, bio-sensing, and others. Prolific Technology also integrates high-sensitivity Hall sensor and driver IC in developing new-generation high-efficiency Smart Fan Driver IC.
