M3802 –2 : EL LAMP DRIVER CONTROLLER
____________________________________________________________________________
Features
• Single 3V 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 steady on
General Description
The M3802 is a poly gate CMOS integrated circuit designed to drive an Electroluminescence Lamp
(EL). Three types of triggering modes are provided. A 3-second delay counter is built-in by internal
divider. The switching and EL driving frequency is decided by an internal RC oscillator.
