深圳市富满电子有限公司 SHENZHEN FUMAN ELECTRONICS CO., LTD. SC1001(文件编号：S&CIC0549) EL LAMP DRIVER IC 第 1 页 共 5 页 GENERAL DESCRIPTION The SC1001 series product is a poly gate CMOS integrated circuit which is designed to drive an electroluminescence Lamp (EL) to light. It supplies three pins for trigger input: one is active at low (ALM) and other two are active at high (TG&FLSH). 3 seconds display delay function is implemented by internal divider. Only ALM and TG will generate 3seconds delay but FLSH not. The switching and EL driving frequency is decided by an intimae RC oscillator. The driving capability for IND output and frequency for EL output are different options, the detail information shown in the OPTION LIST. SC1001 series product can be widely used in the back light of digital watch, analogy watch, calculator etc. FUNCTIONS  Single 3V or 1.5V battery operation.  DC to AC conversion.  Built-in RC oscillator.  Built-in delay function.  Three independent trigger inputs: ALM (L) makes EL display for 3 second delay. TG (H) makes EL display for 3 second delay. FLSH (H) makes EL flash companied with the pluse from FLSH without any delay. (See Tining Diagram)

FEATURES

 Economical solution for EL display.  CMOS process and low power consumption.  No external component needed for delay function.  Min. external components application.

0.001-0.1uF Note: 1. Substrate is connector to VDD. 2. The wires connected to TG and ALM cannot across the lines lnside the black dote line box. Furthermore, these wlres should be separated from the lines lnside the black dote line box by Vss or Vdd. 3. The capacltor C1 can be connected to Vss or Vdd. 4.During the watch application, the two wires connected to crystal are better to be surrou nded by Vss or Vdd, and they are the farer the better away from the wlre connected to EL. 5.
