PRELIMINARY DATA SHEET

LND080A/B

85-347VAC True One-Wire

Offline Emergency Light Driver

FEATURES

GENERAL DESCRIPTION

The LND080A/B are single wire HV

conductor, low cost, solutions for AC

offline emergency lighting. The LN080 is

capable of operating from 120V, 277V, or

347V without requiring the user to utilize

• Offline emergency light interface

• Lowest cost solution

• Includes full bridge diodes

• Universal 85VAC-347VAC Input

• Single wire HV conductor eliminates

need for separate HV input wires

• On board battery charger

different input wires.

This reduces

returns typical in the emergency lighting

market.

• Two on board resistor programmed

current sources up to 100mA

The LND080 includes the offline full

bridge diodes, battery charger logic, and

two resistor programmed current sources

which can provides up to 100mA of

output each.

The LND080A is targeted at exit signs

and the LND080B for emergency lights.

A switch driver and debounce circuitry

allow regulatory tests.

• Switch driver current source with on

board debounce

• LND080A for use with normally on LED

strings (exit signs). Button removes AC

to test battery connection.

• LND080B for use with normally off LED

Button

strings (emergency lights).

removes AC and engages LEDs.

The LND080 are packaged in 10 pin

EPAD SOIC packages.

• LND080B autodetects loss of AC input

and engages LED strings

• Replaces standard transformer or AC

divider solutions

• 10 pin EPAD-SOIC Package

APPLICATIONS

• Exit Signs

• Emergency Lights

• Battery Backed-up Lanterns

• AC Charging LED Flashlights

• AC Charging Helmet Lamps
