Description
The L6384E is an high-voltage device,
manufactured with the BCD"OFF-LINE"
technology. It has an Half - Bridge Driver structure
that enables to drive 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. Matched
delays between Low and High Side Section
simplify high frequency operation. Dead time
setting can be readily accomplished by means of
an external resistor.
