Description

The L6388E is an high-voltage device,

manufactured with the BCD"OFF-LINE"

technology.

It has a Driver structure that enables to drive

independent referenced N Channel Power MOS

or IGBT. The High Side(Floating) Section is

enabled to work with voltage Rail up to 600V.

The Logic Inputs are CMOS/TTL compatible for

ease of interfacing with controlling devices.
