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. FEATURES DC/DC Converter ♦ Input voltage: 2.5V to 4.2V ♦ High efficiency (max output current =100uA) ♦ Output voltage is 10V Package and Operating Temperature Range ♦ 3mm x 3mm 16Pin QFN package ♦ Operating temperature range: 0~70℃ Analog Switch ♦ On-resistance match between four channels ♦ Low ON/OFF leakage current ♦ Vop support voltage = 10V Control Interface ♦ I2C serial interface ♦ Up to 400KHz I2C bus compatibility ♦ Support power down control pin 16K-byte EEPROM ♦ Support byte program and page program ♦ 32 byte page buffer ♦ Self-timed programming cycle (6m sec max.) ♦ Endurance：300K write cycle ♦ Data retention time：more than 10 years Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice.
