DESCRIPTION

Designed in High-voltage BCD Off-line technolo-

gy, the L6382D is provided with 4 input pins and a

high voltage start-up generator conceived for ap-

plications managed by a microcontroller.

It allows the designer to use the same ballast cir-

cuit for different lamp wattage/type by simply

changing the

µC software.

The digital input pins - able to receive signals up to

400KHz - are connected to level shifters that pro-

vide the control signals to their relevant drivers;
