Unisonic Technologies Company Limited was set up in 1990, and it is the manufacturing supplier for high-tech semiconductor devices and IC design, and its products are mainly of Power Management, and Audio Power Amplifier IC, supplemented with Motor Controller, OP, and TR. These components are primarily used in the market of PC, telecom, and consumer products, and they are sold throughout Asian area, while the company also owns direct branch in South Korea, Thailand, and India.

The difference to develop a completely diverse service model from that of previous one in OEM/OEM lies on the fact that IDM would resort to more aggressive manner of approach, and one would have to fully master its independent competence in every critical point from the research and development, design, manufacturing, packaging, testing, and to the marketing of brand name. As such, it would achieve the advantage of productivity security and technical independence, which is different from the commissioned OEM model of domestic vendor supplier and would fully demonstrate its competitiveness.  

The scope of application of its products is well widespread. For example, its power management IC can be used on motherboard, optic-electric storage product, power supply or digital camera and other products; for series products of audio power amplifier, it can provide the customers frequency needs from 0.25W to 35W,

while its functions should include Headphone, mono, Stereo BTL with Shutdown with DC Volume Control

of multiple choices for various applications on Car Radio, Car TV, LCD Monitor/TV, DVD Player, MP3, CD-ROM, Mobil phone, Note Book, and PDA or other wireless equipment.
