Zoom Actuator Driver IC

Model Number

ID9802

Specification

The more mobile phones have diverse functions, the higher technology is necessary. Since Mobile Camera Phone (MCP) has been introduced in the market, customers want much higher performance. MCP can't produce a clear picture with Fixed Focus Lens. When Auto Focus function is imbedded in it, a high-quality and clear picture comes out. In addition, zoom function is another necessity for the vivid image. ID9802 operating with CMOS Sensor and Stepping Motor is the first Zoom Actuator Driver IC. It has an exceptionally high competitiveness in terms of both chip size and package.
