ELM711

Christmas LEDs Driver

Description

Features

The ELM711 is a sequencing circuit that is

• One button controls power and patterns

• Needs no external timing components

• Eight different patterns

typically used to control strings of LEDs on

Christmas trees. No external components are

needed for its operation, as all timing and logic

functions are performed internally.

• Debounced control switch input

• Wide supply range – 3.0 to 5.5 volts

• High current drive outputs

Each high current output is capable of directly

driving an LED, but in order to drive a string of LEDs,

a higher voltage supply and an interface circuit

(typically a transistor and two resistors) are required.

See the Example Applications section for a short

discussion on how you might typically build such a

circuit.

• Low power CMOS design

Note that this integrated circuit uses rapid PWM

switching techniques to perform the LED dimming,

so this device is not suitable for use with slow

interface devices such as electro-mechanical relays.
