Preliminary ST9902 Liquid-Crystal Shutter Glasses Driver 1.

INTRODUCTION ST9902 is an integrated circuit for liquid-crystal shutter glasses driver.

It combines a DC/DC converter that generates a specified voltage level as the output voltage source to the four-channel analog switches.

Each analog switch has a dedicated input control pin and a dedicated output analog pin.

The analog switches can be used as the lens driver in a 3D glasses system application.

16K-byte EEPROM is suitable for the M
