DESCRIPTION

The L6384 is an high-voltage device, manufac-

tured with the BCD”OFF-LINE” technology. It has

an Half - Bridge Driver structure that enables to

drive N Channel Power MOS or IGBT. The Upper

(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. Matched delays between Lower and Up-

per Section simplify high frequency operation.

Dead time setting can be readily accomplished by

means of an external resistor.
