SC6802
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.
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
