SC6802

www.DataSheet4U.com Silan Semiconductors EL LAMP DRIVER IC DESCRIPTION The SC6802 is a poly gate CMOS integrated circuit which is designed to drive an Electoluminescence 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 3 seconds delay but FLSH not. The switching and EL driving frequency is decided by an internal RC oscillator. The driving capability for IND output and frequency for EL output are different options, the detail information shown in the OPTION LIST. TG IND EL SC6802 TES T1 TES T2 FL SH ALM VDD VSS Chip Topography The SC6802 can be widely used in the back light of digital watch, analogy watch, calculator etc. FEATURES * Single 3V or 1.5V battery operation * DC to AC conversion * Built-in RC oscillator * Built-in delay function * Three independent trigger inputs: -- ALM (active Low) makes EL display for 3 seconds delay; -- TG (active High) makes EL display for 3 seconds delay; -- FLSH (active high) makes EL flash companied with the pulse from FLSH without any delay (See Timing Diagram) * Economical solution for EL display * CMOS process and low power consumption * No external component needed for delay function * Minimum external components application OPTION LIST OPTION SC6802-1 SC6802-2 SC6802-3 IND Output Current LOH1(mA) Min.
