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.

Liquid-Crystal Shutter Glasses Driver

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 MCU-based system, which can use EEPROM as a code or data storage unit. ST9902 chip is integrated into a 16-pin QFN package and only a few external passive components are required. 2.
